This 11 hour presentation has most of what you want to know. Feel free to skip parts that aren't related (ufo/alien stuff and discussion about setting up your own radio station).
I also suggest reading his book (make sure to get the non-censored version) and listening to his Mystery Babylon radio series. All are on archive.org and youtube.
The short version: There is a big club of rich people living on this planet. You are not in the club. If you think money holds any value other than control of the population you've fallen for one of their many tricks. Bill Gates is motivated by the (not so) secret society he belongs to. They openly state their goals on their various websites and through their various organizations. Just check out places like the IMF, UN, CFR, and various related organization's websites and read their press releases. They always tell you their plans sometimes 10-30 years or more in advance.
The goal is basically to eliminate the so-called middle class. A class of serfs and a ruling class will be all that exists. The ruling class will rule over the serfs by restricting access to technology, information, and resources. The serf class will continue to become dumber through selective breeding which essentially boils down to eugenics that are the opposite of Hitler's so-called master race plans. Basically, through race mixing, genetic and technological modifications, and poisoning/drugging the food and water the perfect serf/cattle class will be engineered. A class of people just smart enough to do the required manual labor but dumb enough to never question who is ruling over them. The serf class will be reduced in size as robotics and AI gets more advanced. Eventually, all that will remain of it will be the few required to personally serve the upper class. They will do jobs the robots can't or jobs the rich don't trust robots to do (organic humans can't be "hacked").
If you think I'm crazy I encourage you to learn the symbolism and take a look around. You pass by things everyday without understanding the meaning of them. Things like the open air temples that exist in every major US city. Or the obelisks and reflecting pools that seem to dot the landscape no matter where you go. If you're familiar with the signs bums and hobos leave for each other it's a very similar practice. Except in this case it's being done by very powerful people. For example, have you ever wondered why all the major Government buildings seem to have black and white checkered floors? I bet you haven't even noticed it despite seeing it on the news everyday for your entire life.
Go look at Washington D.C. on Google maps.
Red and Blue teams do not really exist. It's just a show for the pleb class. Money doesn't mean anything to the rich, it's just a tool to control the serfs. Charity does not exist for these people, it's just a tool for good PR and to do research on otherwise illegal areas. Christianity, Judaism, and the other pleb religions are not followed by the upper class no matter how hard they pander to those groups. The upper class follows their own secret religion that basically boils down to Satan worship.
Why satan worship? I'm not really sure. If you read their books they like Satan because they believe humans were living as God's slaves in the garden of Eden until Satan gave us knowledge. They believe Prometheus and Satan are the same entity (he brought us fire). They believe we should become God's ourselves and with the knowledge combined with the combined efforts of the illuminated ones they will eventually obtain this goal. Indeed they've been working towards it for thousands of years if you do your research. This is not fiction, just pick up a dictionary from the mid-1800s and look up Illuminati. See what it has to say.
Lately, we've seen a crack down on free speech on the internet because these facts (among others) were becoming to well known to the serf class. Since outright censorship of the internet would result in violence and uprisings we're seeing them use other methods: propaganda, 24/7 gaslighting, mass bans, and the use of paid posters and bots to flood every platform of discussion. Many have bought into the propaganda and believe they're doing the right thing by helping push this agenda. This is why we see retards that believe they're fighting against the system while being fully supported by the system.
What motivates Bill Gates? Being part of the great work. Being immortalized in the stories about the great work. The dream that someday the illuminated ones will become like Gods. Gods that live forever and rule over the pleb class who must be treated like children because they're to stupid to exist without a caretaker. This is why they hate the concept of God so much and do everything in their power to spite him.
If the above isn't their goal then the only other option is this: They're attempting to piss God off and bring about end times as soon as possible. If this is their goal maybe you could consider them the good guys. But in my opinion they're pure evil and so high on their own farts they believe they're right no matter what. This is probably why they're so bad at what they do.
Gate's is right about one thing. Land is the only thing of real value on this planet. If you're smart you'll buy as much of it as you can while it's still possible. Just be prepared to defend it because soon private ownership of land is going to become a hot button issue.
