Who are the Rich?

[CCass]

In the "Unions are Evil" thread, Whiskeytown stated that only a rich person could be anti-union. It always bothers me when the left assumes that anyone who agrees with many (or most) of the conservative "issues" must be rich. I have some libertarian leanings, but I definitely tilt to the conservative side. I have never considered myself or my family to be rich (when I was growing up, my sister and I qualified for the reduced price lunches at school), yet I am a conservative.

So, at what household income would you define as "rich"? I am married and have 3 children, and live in a city of about 30K in Middle TN.
