So what? My wife and I paid a lot in taxes. It seems to me like you're a whiny spoiled kid who only wants to point out the negatives in life in relation to their wealthy lifestyle. I went to a small rural public school, a public university for my BA and MBA and self-study for my CFA charter. Both my parents were union workers, albeit college educated, but they didn't give me much support.
Somebody paid the taxes to build the infrastructure to operate your business. Somebody paid taxes to make your school (if public) operate to get your masters degree. Somebody paid taxes, likely higher, to allow your parents to be educated.
This country is about building our people up through infrastructure and success. If you want to look at rich people not doing this, go to the ME and see how easily it is for rich people to horde their money, not invest anything in their people, and allow them to wallow in poverty.
Your examples of the "escalade" and "welfare" are hyperbolic bullshit. For every one person who abuses medicare or welfare are 10 people who don't. Think of the kid who isn't dead because of medicaid.
I deal with self-centered rich assholes all of the time. The more wealth they get the more they forget how it was to not have wealth. It's disgusting.
