Well put. However, the capitalist class often does not act coherently as a whole, as intra-capitalist competition and temporal short-sightedness can hamper their ability to influence (let alone fashion) political policy in terms of their shared, long-term interests.
w/o a doubt! 'Capitalist class' is really broad tho, and wrt that link, the IMF is about as high-up as you can possibly be in the global-economy pyramid*, so it does set the tone from the top-down in a big way, and i'm happy they(IMF) see it that way – not just because it's the way it is, but because of the influence they wield. I'm also aware they're not doing this for the welfare of humanity, or for our planet/environment, but solely because it's more profitable for their fund (I find it incomprehensible they do not care about their fellow man/planet, I just mean that their primary concern, as an organization, is the organization's financial well-being. I make this distinction because I think some see them solely as vampires lol)
(*there's no way to say who's 'highest' because at that level you have to consider governments as well and, obviously, many ppl are both 'gov' and 'private finance', so the overlap is considerable)
I should add that 'intra-capitalist competition and shortsightedness' are, in many (subjective) ways, better for humanity. Just because the IMF finds that decreasing inequality is better, does not mean that other long-term ambitions of a different, cohesive 'capitalist-elite class' would be seen by anyone outside that class as being good, I mean i'm sure we can all think of tons of examples of long-term cooperation by such classes that only benefit them, to the detriment of society-at-large (I feel it's important to note that if, somehow, we could entirely detangle government / business 100%, almost none of that would matter; it mainly hurts society when private business interests can corrupt government, in many cases to the point where the actors swap between those sides regularly)
It seems that it's more during times of economic crises that capitalists succeed in such, I hypothesize on account of shared threats (both in terms of imperiling economic conditions and systemically destabilizing unrest from a proletariat who organizes for survival during crisis).
I'm interested in hearing more from you on this, I mean I can think of so many examples either way and haven't noticed any correlation (it may be hard, as 'capitalists' could be russian gangsters pwning the former ussr after communism died – preserving their long-term during a crisis, or the american financing industry sabotaging itself during our housing crisis [although some groups, those w/ government-favors, actually did secure their long-term survival- there are a couple banking outfits that have gotten stronger through several financial disasters, through political influences of course])
