It's supply and demand. If there is a greater demand for workers, then companies will pay more for them. If there is a surplus of workers, then companies will pay less for them. There's nothing wrong with that. A free market will always pay people what they're worth.
Minimum wage is like price-fixing, which historically has always created shortages. Minimum wage creates a shortage of jobs available.
Bottom line: The more government gets involved, the more problems they create.
Many businesses here in Cali liked the surplus of workers from Mexico. It kept wages lower at American's expense. The Republicans are all for supply and demand, until businesses must cough up more money. Then those same Republicans are for open borders, to increase the supply of workers, and lower wages.
It's already a fact. Even with minimum wage increases, people are getting farther and farther behind, due to inflation. A gold standard would help keep prices in check. That's certainly much better than what we have now, steady inflation that's destroying everyone's wealth, except those that can vote themselves higher pay (politicians, BODs, etc.).
The same problem happens in housing. A shortage of housing causes higher prices. When it comes to a single family home, historically, you weren't going to qualify if the mortgage payment was higher than 30% of your salary (gross or net??). This actually has the effect of keeping prices lower, but if you've got to live in an apartment, there is NO limit as to what property owners can charge. Because you must live somewhere, you might be forced into paying 40-50% of your salary. As long as there are people willing to pay, with a better job than you, they can drive out the poor people. To get around the high prices, many people are forced into living conditions they normally wouldn't tolerate. This in turn keeps prices high as people try and cope with the existing high prices. Some places have rent control, but the property owner's say it hurts them, so in conservative areas you won't find any rent control.
Sorry for the tangent, but all of this seemed somehow relevant.
