I don't have any fundamental problem with taxes. I have a problem with property tax (where I must keep working and paying it or I lose my house). There are many instances of older people who bought waterfront property here many decades ago and then were forced out because the property taxes got too high for them to afford. It's wrong. I also have a problem with "used item" sales tax. When a person here buys a car, they pay 10% of the price as sales tax. Then when it's sold used to a private party, that private party again has to pay sales tax on that used item. The state keeps taxing the same item over and over. However, there is a government-sponsored scheme wherein if you trade your car in at a dealership, they reduce the amount of tax you pay based on the amount your old car was worth. But if you sell your car on craigslist, and then buy another off craigslist, you don't get that discount, which is asinine.
Anyway, regarding the definition of rich: if it's really not about how much money you have, but rather, how you got it, I think a different term is needed. I have no ill will whatsoever for people who go out and make some stupid app and earn 100 million dollars. I have no problem with athletes that get paid a ridiculous amount of money to play ball.
I do have a problem with huge corporations (and those that lead them) that don't follow the rules, don't pay their fair share of taxes, **** all over the environment, **** all over the little guy, etc. It seems like the problem is more the abuse of wealth and power than the having of money itself. But we can't point the finger solely at the rich guys when the government colludes with them to maintain the status quo. Government-sponsored monopolies (cable/internet companies, landline phone companies, wireless providers, trash collectors, etc.), greedy, competition-stifling regulations (prohibition of community broadband, lame car dealership requirements prohibiting tesla from selling cars direct, etc.). My point is that it seems to me the problems could be helped if the government had the balls to actually govern, and do what is right and good instead of protecting entrenched players.
