@coluber2001,
I travelled in India, where they are trying to get rid of the class system, untouchables being the lowest. I think the term lower class has always been derogatory and ignorant, because it doesn't take into account class at all. Working class makes sense to me.
However, I'm not the one who made it about laziness, you did that. Saying that people who are not financially on par with the rest of society because they don't want to work or never will was your contention, not mine. I find that ignorant as well. Perhaps if you'd thrown in a few smiley faces it wouldn't have been so distasteful to my ear.
Bernie Madoff, one of the richest men in the USA, had a high class lifestyle and left many of his victims broke. Are his victims a lower class than him? And why in god's name would you consider 'working' a derogatory term? It's what most of us do...
