Sorry to take so long getting back to you, I've had internet problems all week.

Now, it certainly isn't a source of any pleasure to me when I observe that in North America, and especially in many parts of the U.S., the class system has been evolving for several decades in a direction where there is an increasingly wide and severe chasm between the growing underclass and the middle classes

I'm somewhat familiar with Charles Murray's research on this subject, I assume you are too. But he has argued that the middle-class' efforts to separate themselves from the underclass make the situation worse, not better, because they make it harder to middle class culture to spread to the underclass, and he has advocated attempting to close the chasm in various ways. By contrast in your original comment you seemed distressed that it was so financially difficult for the middle class to separate themselves from the underclass and I got the impression you wished it was easier. Do you disagree with Murray, or was I drawing an incorrect inference from your comment? Feel free not to answer if you think doing so would break the "no discussing politics" rule.

You characterize my statements as "off-putting," but you don't indicate what exactly you find inaccurate about them. Do you believe that I'm exaggerating the above described phenomenon? Or do you think only that I should be expressing myself more diplomatically about it?

What I find off-putting is primarily that they sound rather political and we aren't supposed to discuss politics at Less Wrong. If you were making the point at some politics forum I wouldn't necessarily find it off-putting. Admittedly this sort of discussion is something of a gray area since it's hard to discuss this type human social behavior without mentioning ideas that are parts of major political ideologies. I am reticent about voicing my personal opinion on the accuracy of your description is because I'm afraid I'm skirting the edge of political discussion already.
