I completely agree. My point was that, without some extra source of money, forcing employers to pay a particular salary won't work. We need to make it possible to live without a salary.

You may agree in principle, but you are using terms like "forcing employers" which contains a built-in bias. Here's the same question with a different bias: "How do you restore power to the employees so they get equitable salaries?"

Your question assumes that what we have now is natural, and that force is required to change things.

If the shop owner's thumb has been pushing down on the scales for years, then the solution is not that the customer needs to apply an opposite force to balance thing out, but the shop owner needs to stop applying force.

(Okay, applying a counter-force, as in Leslie Thrasher's "Tipping the Scales", would be a short-term solution, but it's also an easily corrupted one, and it makes most of the people feel like they are being ripped off.)

To start the answer to my question, first remove so-called "right-to-work" laws, or at least the legal requirement that non-members can "force unions to provide without compensation grievance services that are paid for by union members." (Quoting Wikipedia Right-to-work_law#Unfairness .) There's plenty more, but it's a belabored topic that you can easily find elsewhere.
