"Ever heard of minimum wage? Yeah, that one did not work as expected either (and created massive unemployment when the threshold was set too high as well)." Citation needed. Your assertions do not match my understanding of the facts about the result of the minimum wage. (Though I would have agreed with you ten years ago, a better understanding of it has altered my opinion significantly.)
When you raise the minimum wage, you don't change any of the other aspects of the business affected by it. So, say you have 15 employees making $10 an hour to keep your company afloat. (Just to keep things simple ,this is about the logic of it.) Now the minimum wage goes up to $15. What are you going to do? You would be losing money with a %50 increase in your costs. Most likely what you will do is lay off 5 employee…
That is a loaded question. The minimum wage does not have to be increased to some ridiculous amount, but it does have to be high enough to keep the people off of government benefits.
Additionally, if raising the minimum wage by a modest amount causes a business model to crash and burn, then that's a flaw which needs to be corrected. Maybe that business model wasn't so robust after all?
If a business depends on an exploitative minimum wage to be profitable, that business needs a new business model. If that means more automation and robotics, so be it. It is not good public policy to pay exploitative wages that force employees to go on government assistance at the expense of the taxpayers.
