Something you're fundamentally not getting: capitalism argues that a job is worth whatever the market will bear. Socialism argues that a job is worth whatever is necessary to provide a living for the worker.

Extremes in either direction don't work. We've got a hundred years of history demonstrating this. However, every problem on this page is the result of markets being favored over society. And you say things like this:

and an overpaid grocery bagger is much worse than a person given a living wage for free.

That are offensive and nonsensical.

Why.

For what reason.

Because the job of bagging groceries has not changed, and it used to provide a living wage. If you're in a union, it still does. And maybe I'm a bleeding-heart liberal but as far as I'm concerned, if someone is going to spend eight to ten hours a day performing labor in a market system, they deserve enough to thrive. And if automation and advancement eliminate those jobs, then whatever jobs there are should pay more, not less, because it's in MY best interests as a member of this society that it not collapse under the weight of millions of idled workers fighting for scraps.
