I find it odd how many vilify and decry people of wealth. If it was earned legally then more power to em!
To be honest when someone has gone from nothing to much they often have things we can learn from them and habits that can prove success is with in reach.
But having wealth is not always easy street either. They have their own temptations and fears just as anyone else. Many die from drug abuse, some fear things they have no control over like their health. I have seen some held prisoner to it.
Envy is just as bad as anything they are doing.
As for the cars I enjoy seeing them and reading about them. I will never likely own an exotic but never begrudge anyone that does own one.
If not for even some folks who buy them for the wrong reasons they create a market do the cars exist and we can see what really can be built.
