There are somewhat hard limits on the availability of labor though. I know a guy who owns a very popular and expensive restaurant that had to start closing one day a week because he couldn't find enough staff, and not because he pays them peanuts.
Not paying peanuts still doesn't mean it's enough.
Anyhow, my opinion as someone in the restaurant business, the blogger's business had plenty of flaws.
That's what I wrote.
If your friend can't find enough people then the wage he's paying is less than the market-clearing price.
Doesn't matter if you or I think their pay is peanuts or not.
When the market price of coffee increases, coffee shops don't cry that they can't find coffee, they pay the higher price and then they raise prices.
But when the market price of labor increases, employers don't raise their wages, and then they say they can't find workers and can't afford to pay more.
Why is labor pricing treated differently from any other economic input?
