My wife and I both working; Our incomes are in 95% pecentile according to IRS; Owning real estate beside my own home in a suburb; Have 2 cars; 2 kids( daughter and son); 30 days vacations for each per year. We do not call ourselve 主流 class. But according to IRS and Washington politics, we are what they called "rich people". I never believe that. When I check out, I found out that how much decide you are rich or not in every Presidential election season like now, which will put you either in Democratic or Republican party on economic term is ( you are ready for this ?) $35,000 family income! Do not laugh! It is true. It means that if you earn more than that, you would more likely vote for Bush or vote for Kerry.
My wife and I combined earn several fold of that. But I never called ourselve 主流 class. But there is no such thing in America
