I'm gonna pay my low-end employees 2 bucks an hour this summer.
That's a low amount. Why wouldn't you pay them more money?
Because my employees work only 20 days a year and they have low living standards
You are being ridiculous. You need to pay your employees a living wage if you wan workers at all. Otherwise, they have every right to walk out on you.
Maybe I'll just hire kids instead.
Regardless of the age of the people you hire, you have to pay a minimum wage. Aside from meeting the government's minimum wage, it's good to pay people an amount that they can survive with. If you don't pay your employees well, they won't do a very good job.
