Personal Finance and Investing

you are lucky, you should not worry about your future, but my question still remains. Mostly I am trying to get a fix on what we mean when we say tax the rich. I think the majority of us think of the very wealthy, and not the just entering that area. So we tax the "rich" and I get the feeling that the upper 1% of the 1% will avoid the tax and the upper middle will carry it the tax. So when the collective we discuss taxes on the rich whom do we mean, ergo who are the wealthy?
