Sorry, was out for a bit...
I was a wee one in the 80s, so I honestly can't say I observed the middle class changes for a long time, as you and others here have. I've observed that we've found ways to replace workers with machines that run more efficiently (computer programming will remain a hot skill for as far as I can see), replace full-time workers with part-timers, and offshore work to countries that pay their workers much more cheaply.
With all this change and job uncertainty, it'd be nice if we had free health care for all, paid for by increased taxes on the top who own a great deal of our citizenry's overall wealth. I'll go as far as saying I'd cut the welfare program that GOP folk tend to dislike if it meant free healthcare for all.
