Many have responded to that question.

I am unqualified to do so. However, I have checked out a few sources, listed below.

First, three brief comments:

1. Many jobs required by union contracts (i.e. “featherbedding”) should have been eliminated decades ago.

2. Many other jobs (e.g. roofing, food services in restaurant and hospital kitchens, lawn care, housekeeping in hotels and motels) are now taken by people who cannot obtain employment elsewhere.

3. These are the same jobs that many unemployed high school and college graduates consider “beneath them.”

Here are some links to sources worth checking out:
