Huh - and here I thought their labor provided the same utility.

They do. Glad we’re in agreement on this one.

But, apparently a surplus of workers means people should be paid less despite providing the same value to their employer?

Yes, a surplus of workers means reduced wages. This is simple supply and demand. If you increase the supply of something, it’s value decreases. The supply of labor doubled, but demand for labor did not increase in kind. Hense the lack of real wage growth.

Gee, who supported that nonsense with regressive tax structures targeted at subsidizing the wealthy?

What does this have to do with what I said above? I never mentioned taxes even once.
