Much of this, indeed the lion's share, could be fixed by reordering the economy to be Distributist.
So why is that important here?
Because what people don't have, is well. . . anything. People are consumers, and servants. They lack something of their own, and they accordingly lack stability. Increasingly, on certain things, including economics and science, they lack education.
And, like the ignorant and have-nots tend to be, they're unhappy and made.
The unhappy and mad masses always make for ignorant revolutions, whether it be the French Revolution, the Russian Revolution, or the revolutionary period of the Weimar Republic that concluded with the Nazis coming to power. Not having anything, they're willing to try something, whether that something be Vladimir Lenin, Adolf Hitler, or Donald Trump.
It was Jefferson who noted that republics were grounded in yeomen farmers, for the reason that they were independent men. Through Corporate Capitalism, we've been working on destroying the yeomanry for quite some time now.
The failure of people to have their own has been significant in creating the crisis that we face today. People who worked for other entities, and that's most people, find themselves either adrift without them or slaves to them. People live where they don't want to at jobs and careers they don't want to, in conditions they don't want to, even if they do not fully realize it, as their corporate masters compel them to. It gets worse, all the time, and people are powerless against it.
Indeed, not only are they powerless, but they can be compelled to act against their own best interests, and often do. People who love one thing as their true selves, will work to destroy the ability to do it for their corporate masters. You don't have to look much beyond the Wyoming legislature to see this, where some advocate policies that would deprive average Wyomingites to access to public lands, for example, something that only serves the interest of the wealthy.
What does a Distributist Economy look like?
So, what about agriculture, and this agrarian thing?
