Loaded question, but more yes than no. In the end, wealth for the median is a function of the size of the pie, and that requires rather vigorous supply side policies. The most critical of those is revamping our secondary school system from root to branch.
The whole point of supply side economics is to mask the fact that most peoples' slice of the pie is shrinking by increasing the size of the pie drastically...
And as far as revamping our secondary school system into a technical training period for specific jobs.. bad idea. Teens need a basic education that focuses in core skills that can be used in almost all job situations. College is what specialization is for. Just ask the Germans what they think of their 3-tier system? It's just working swimmingly, isn't it?
