And we should subsidize vocational training to a greater extent so that students aren't forced to take on financially crippling loans.
The biggest issue with your proposal is that if those employees paid by the government to do these jobs are paid less than the private sector, you'll put the private sector out of business. If they're paid the same or better, you would need strong incentives to make them go find a different job instead of keeping a market rate job that is assured to never go away.
I would propose that the temporary government employees be paid minimum wage. This isn't intended to be permanent.
There's quite a few jobs for which the government rightfully has a monopoly. I certainly wouldn't want the fire/police forces to be private. We had that and saw the problems it created. Same goes for the military. I'm not aware of an example of a private IRS or judicial system at a national level but I can't possibly see that going well either.
So yes it's a matter of degree but I disagree with you strongly on where to draw the line.
There’s no credit given for having a tidy business with steady profit. Instead you have to have “growth” and other this-quarter-must-be-better-than-last-quarter-or-else crap that “investors” want.
Small businesses are often able to get credit in the form of bank loans once they have established a track record of profitability.
You are in a tech bubble. Absurd profitability is not required elsewhere.
Simple example: The real, measurable costs of pollution - illness, polluted drinking water, etc - are externalized and so companies doing said polluting are "profitable." Would they still be profitable if those costs were not externalized? I suspect not.
Similarly I suspect there are externalities not being accounted for, for self-interested reasons on the parts of those collecting the profit, when assessing which types of work are profitable or not.
