Sure, but this goes both ways.

Expecting someone to quit McDonalds or being a waiter to go code or install HVAC might work on an individual level, but it would be a disaster on the societal level as many of these jobs while being poorly paid, are necessary for society to continue to function.

Of course the moment the "free" market doesn't act the way corporations want it to, they spout one liners such as:

"Nobody wants to work anymore."

"Why are the restaurants closed?"

"Why are there no tradesmen?"

This is why worker rights are important and shouldn't be neglected.

Sure, it might be easy to replace the local McDonald's janitor, but what about the railroad workers?  Ignore them and the economy grinds to a halt.

That's not how supply and demand works. If fewer people are willing to do those jobs, then the pay for those jobs will increase. Jobs that are "necessary for society to continue to function" will never disappear. 

It's "peak oil" all over again.
