Re: When you stated...
You left out sentence #2 where I said something about when statistics show the opposite -- that is when the middle-class grows while the poor and rich shrink. It's just a fluctuation like the stock market going up and down.
I did not make any claims about trends -- that would take research on my part.
Last sentence a quote from the song "Aint we got fun": "The rich get richer and the poor get children; In the meant time; In between time; aint we got fun?" From memory, so forgive any inaccuracies. Sorry for the obscurity.
