RE: Are we oppressed by capitalism or just ungrateful?

No economic system is perfect but I don't think anyone has yet come up with one better than free market capitalism. At worst, people are selfish, At best, they have an enlightened self-interest. Either way, capitalism does the best at harnessing that instinct for the good of all. Again, not perfect. Just (a lot) better than the alternatives. I think it will remain so until we get to a Star Trek level of virtually unlimited resources. Who knows...with the advancement of AI, perhaps we are on the cusp. Also, an economic system shouldn't be confused with charity. It isn't.

While I have libertarian tendencies, I am not an anarchist. I wouldn't suggest that there should be no laws. As such, laws curbing the worst excesses of capitalism are fine (e.g. exploiting children). But let's not throw the baby out with the bathwater or pretend that other economic systems are not exploitive. If there is a way to abuse something, someone will find a way. Also, government regulation has a tendency to limit competition. Again, not suggesting there should be none but government really has to have a light touch when it comes to regulations and they need to be well thought out. Often they are not...or worse they are written by lobbyists...then you start getting more into corporatism than capitalism. Capitalism without competition isn't really capitalism...or not a free market variety anyway.

Blockchains are just a new technology...a new tool. They are not inherently pro or anti-capitalism...that's more on how they get used.
