Relevant/Accurate Facts?
Many of the facts or generalizations are in fact opinions.  For instance, the suggestion that one million dollars is needed to live in the US without working is highly subjective.   (one could live on $500,000 quite easily, based on the average rate of return for conservative investments like mutual funds.)  Furthermore, actual cash is not necessary - many people live comfortably on businesses worth less than $100,000 that they own.

Also, using Marxist language in the initial definition shows a political POV, as in "The main defining characteristic of the working class is its dependence on wage-labor (or salaried employment) as the main or only source of income, because of lack of capital assets or land that could provide an alternative source of livelihood."  In reality, one could argue that the main defining characteristic is simply whether one is in management or whether one uses physical labor or 'brain' labor.  In today's economy, it is not simply the lack of capital assets or land that may indicate working class, but also a lack of marketable knowledge.  You can own 100 acres of rural land in most US states that would be impossible to earn a living on, while having the right knowledge could earn you a living anywhere.

Finally, the alleged sexual habits of the working class (citing research 57 and 32 years old) is irrelevant to this article unless we are going to take the ridiculous practice of defining working class by their sexual habits.  Also, judging certain sexual habits as sophisticated shows a POV and this whole section is childish. 01:11, 16 October 05
