If the federal minimum wage is raised, where will the companies get the money from?

Their cash flow - - if they can't afford it they're in serious trouble

In Ontario Canada the minimum wage is $14.25 an hour. In Alberta the minimum wage is $15 an hour. How can Canada do it and the USA can't?

Small businesses already have a hard time competing with giants like Amazon. A big minimum wage increase will be the nail in their coffin. I don't want Amazon to be the last company standing. We should support mom and pop stores. 

Who cares ? If a company cannot or will not pay a living wage, then basic capitalism says that it is a BADLY run company. And, it will be replaced by a BETTER run company that can make enough money to BOTH turn a profit AND pay decent wages.

Why are you such a pervert that you would steal from the poor workers just to inflate a company's profits ? That's hugely immoral and stupid.

The minimum wage should be around 20 bucks to account for inflation 

For non-profits the same place they get it from now, through donations and fund raisers.
