IF wages are to high thats because cost of living is to high. When you can buy a coke for 5 cents and a car for 2000 dollars, a home to live in for 23,000 dollars Maybe you will see wages dropping.
If there are too many looking for work, will it become that there are 20 applicants when a minimum wage job comes available? Will we end up employing the huge majority of workers at minimum wage?
This question is a non-question. there's nothing different between industry getting more productive, and agriculture getting more productive since 10,000 or more years ago. what will happen with more productivity> a richer nation as a whole. more jobs in the tertiary sector, especially leisure.
Government will pick up the slack. Bigger government, higher taxes (just look at Britain). I am sure the IRS is aware of the wealthiest individuals/entities...that's power, whether good or bad, who knows?
Didn't Margaret Thatcher once make a comment about, "... the problem with Socialism is that the wealthy eventually run out of money..." ??
