The minimum wage turns the working poor into the unworking poor.
They should COLA the minimum wage - as they have done to their own incomes.
Some of them, certainly. Especially if it's increased by $2/hour. A lot of people who are making minimum wage—arguably, most or even close to all of them—simply aren't doing work worth $2/hour more. If they were, chances are they'd already be making that kind of money, either where they are or somewhere else.
If I'm an employer with 10 people making minimum wage and I'm told I'll eventually have to pay them all $2/hour more, I'm going to let go at least one or two of them and expect those remaining will do more work to earn that higher wage. If they can't do it, I'll have to find people who can. It's either that, or raise my prices and lose business (and layoff more workers). Anyone ought to be able to understand that.
But, none of that matters to the well-paid union thugs whose contracts include an automatic wage increase whenever the minimum wage goes up. I'm sure it doesn't matter to their Senators, either.
