Zorn:
>>It's useful I think to first lay out what the purpose or goals of the political system should be; and then to talk about the practical questions of what system best achieves those goals. (If we disagree about the first, we're having a philosophical debate and may never agree with one another; if we disagree about the second, we're just having a purely practical debate about what the facts suggest.)>>
Good point. But how often do we tend to disagree over the former?
>>
In my mind, the ultimate purpose of a political system is to seek two goals: first, upholding the freedom (or autonomy) of its members, and second, working for their common good. Sometimes these two goals will be in tension, and a good political system will have to come up with a balance.
>>
What about maximizing each individual's "good" (utilitarianism)?
The other ultimate ends I can think of are kinda wackier (piety, "progress", coming to better understand the universe, etc.).
>>
By freedom, I mean several things. There's the freedom of people to live their lives as they choose to live them, unconstrained by the threat of force -- either from the government or from others. There's also the practical requirements for that freedom to mean anything; people should not be trapped by social or economic arrangements that drastically limit their opportunities. They should have the resources and opportunities necessary to have some control over their life.
>>
Fair enough. But what constitutes force? And what if the context of a monopoly of force (which is routinely applied) serves as a precondition for non-coerced (genuinely or superficially non-coerced) social interactions?
If we think of freedom as autonomy, I think that there is a great deal more than this "non-interference". Wouldn't maximizing autonomy be maximizing the available courses of action that one could take (or latent self-potentials that one could actualize), these courses of action constrained primarily by factors internal to the person (think auto-nomos), minimizing outside barriers? You seem to take a bit of this on in the second half of the above quoted paragraph. . .
>>
The common good speaks for itself.>>
Oooh, not quite. Happiness? Wisdom? Progress? Some system of virtue? etc. . .
>>I think those are the correct goals for a political system: what all governments everywhere should seek to accomplish. I'm curious, do others agree that this should be the purpose of a political system?>>
In general, I agree (nitpicky critique is my "shtick"

).
>>These two goals of freedom of the common good, along with balancing act necessary between them, to me are the essence of liberalism, and are the starting point for my political philosophy.
>>
This gets more complicated though. Freedom as "freedom-from" lends itself to liberalism (the state acts as an arbiter of interests). But if we think that political autonomy is important, or civic responsibility, etc., all possibly within "the common good", we have to stray a (tiny) bit from liberalism. I should also add that diverse thinkers, from Marx to Rand, operate mostly within the terrain of liberalism.
>>Representative democracy is the best form of government currently known. Because it's so easy for those in power to become corrupt and self-serving, we need to keep governments accountable as much as possible. Democratic elections are a way of doing this. They're extremely imperfect, but they do work. And so representative democracy provides a much better way of constraining governments, holding them accountable, keeping them honest, than any other known arrangement does.>>
This sounds sensible. However, the measures necessary to ensure that representatives represent (and represent the right people) might entail an utterly radical restructuring of politics. Also, there may yet be other, fruitful methods of political organization that we have yet to try.
>>Market-based economies are by far the best currently-known economic arrangements. No other economic system has come close to the market-based economy in generating wealth and prosperity, in giving individuals the freedom and economic means to gain some control over their lives. Until we discover a better system, we should stick with a fundamentally market-based system.>>
While none of what I'll say directly contradicts your sensible declaration, I must add some nuance:
1. Free-market capitalism and state-bureaucratic economic planning are not the sole alternatives.
2. Some socialist variants include markets (but not capitalist markets).
3. Many economic models have not had their experimental test (although failed tests wreak severe problems)
>>We should extensively regulate this system to maximize people's welfare and freedom. The government should use as non-intrusive means as possible (e.g., redistributive taxation) to promote a fair, relatively equal distribution of income. If possible it should guarantee universal basic services to everyone: support in old age, health care, education, and a good deal of social support. It should intervene aggressively to correct flaws in the market system, as long as those flaws are amenable to solution.>>
Again, sensible. However, does redistribution remove the incentives that effect productivity and innovation?
>>Governments should be limited and subject to checks on their power. (The same should apply to other powerful organizations.) All concentrations of power are subject to abuse, and those in power convince themselves they're acting for the greater good. So it's important to keep limits on those in power, to keep what they do open and subject to scrutiny. Utopian plans which involve granting despotic powers to a governing body are generally doomed.>>
But what sort of checks would reign in abuse of power effectively? What about when one concentrated power (the state) is used to reign in others (capitalist firms)? In
Political Parties, Michels argues that these problems are insurmountable.
>>So as you can see, I think the current systems in Western Europe, Japan, South Korea, Aus/NZ, the USA, etc. are relatively close to the best known system. At no other time in human history have so many people been so free and so well-off. These systems are by no means perfect, but they're far superior to the systems of the past, and they're far superior to any other system that's been tried.>>
I think that this is based on an epistemological misconception. We have a world economy and politics play out on an international scale. Much of the prosperity of the nations that you note depends on deprivation of the Global South/Third World. These disparities were born initially out of imperialism, but the spread of democracy and markets doesn't appear to be fixing things.
>>So I disagree vehemently with suggestions for massive overhaul of the current political system. To be worth implementing, a political/social/economic system has to work, and it has to work in the real world, with real people and all their flaws, attempts to game the system to their own good, and so on>>
Like I said: we don't know what works 'till we try it.
>>I think we should have much more progressive tax rates, and greatly expanded programs aimed at greater income equality. There's no "natural" ratio between the salary of a poor janitor and that of a rich CEO or doctor>>
Hear hear!
>>I think we should have a publicly-guaranteed universal healthcare program, along the line of France's or Australia's. I think we should have universal child-care, obligatory parental leave, and other policies designed to foster both gender equality and good childcare. I think we should scale back copyright laws, and perhaps switch completely away from "copyright" to a library system, where all works are available for free, and artists get paid from a taxpayer-supported fund depending on the popularity of their work. I think we should open up our borders dramatically, and let far more people who wish to immigrate do so. I think we should implement a serious policy to deal with global warming: either a steep carbon tax or a carbon cap-and-trade system with auctions and no loopholes. Etc.>>
I'm with you on this too.
In sum, you sound like me when I put on my "liberal hat".
