I always love looking at things like these because they really throw reality into a tailspin by not actually explaining methodology to well. As far as income goes they are ranking you based on earned wages, in otherwords whats the number on line 7 of your 1040. The truley wealthy believe it or not have very small numbers on this line because the majority of their wealth comes from family money and investments. They don't generally "earn" much. Thats why income of $100,000 will put you in the 95th percentile or above. This is why congress, and Democrats say that with income at that level, you are rich and not entitled to tax relief. The reality unfortunatley is that making that much money a year does not make you rich. Granted it is a lot of money and there are millions of Americans who dream of making that much money but I can assure you it does not mean you are rich. The trueist indicator of wealth is in fact net worth. Net worth measures your ability to save and accumulate wealth over a period of time. You could be unemployed for several years and finally get back in the game making $100k a year and not be wealthy. The education and career field being a measure of class is just ridiculous. If you want to discredit the whole theroy of the Times piece just read "The Millionaire Next Door" sometime and look at those guys. They are owners of junkyards, plumbing companies, pest control companies etc. They have little more if anything beyond a high school diploma. They have worked hard, saved well and lived far below their means to accumulate large amounts of net wealth. On a net worth basis the under accumulators of wealth are doctors, lawyers, and professionals whole live in the big houses and drive the expensive cars and cannot seem to accumulate wealth any where close to what the other guys can.
