Yep.
I am pretty sure my company, and boss, never gave me a raise because they thought I was cute.
And as soon as I wasn't needed, out the door I went! "Don't let the door hit ya..."
Basically, companies pay the going rate. The labor market has always been this way, at least in for-profit companies.
If Henry could have paid $2 per hour with satisfactory results, he would have.
Supply vs Demand. In this case, the employees are providing the supply and employers are providing the demand.
As a given wage increases, supply will follow. More people want that job.
And nobody wants unhappy workers as productivity suffers. And every employer knows unwanted turnover hurts.
