My key takeaways...
Some people are smarter, stronger, and work harder. We might not always like entrepreneurs, but when we reward them, they can benefit society with their ingenuity, creativity, and productivity.
However, too much income disparity can lead to communism/nihilism. When communists kill the entrepreneurial class, there is a brain drain, and everybody suffers. Any wealth goes to a few people at the top, with infighting and even more income disparity than before, and the process repeats itself.
The US has a balance between social programs and a private sector economy. People may disagree over whether socialism leads to communism, and whether communism leads to dictatorship. The book has several examples of communism leading to dictatorship.
It is in the self-interest of rich people to prevent too much income disparity. If the rich people are capitalist, this prevents them from being killed by communists. If the rich people are communist, this prevents them from being killed by other communists. It's all about balance.
It's in the interest of everybody to have a balance between trade secrets and transparent processes. We want incentives for entrepreneurial ingenuity, but we also want to avoid a brain drain when it comes to essential goods and services.
When communism turns violent, it is crucial to fight back, but we want to do everything in our power to make sure it doesn't come to that. This means educating the people, and pushing back aggressively against communist ideas. Freedom of speech, yes, but rejection of communist ideas.
The communists hate Christianity, they hate the family, and they hate free creativity in the people. The communists want to destroy time-honored tradition and wisdom so that they can dictate what is right or wrong.
The communists have infiltrated every aspect of government and society. They've been working at it for decades. They control the mainstream media. We all have a duty to understand this and to push back.
