If there was no minimum wage, wages in some sectors wages would drop to where they are in the undeveloped world aka $2/hour. Little communities with favela-like structures with limited heating/electricity would pop up, and if you think the 'dollar store' is cheap, then wait for the '25 cent store' where they sell stuff as they do parts of India and Brazil.
It's funny how people don't think this could happen in the 'modern world', I suggest they don't know what makes the modern world modern. For a hint, go to where the illegal workers in Cali or Texas live and exist. Those communities resemble pretty much the standard of living of Central American countries, aka 'down the economic ladder'. Because they are.
Moreover, having secondary low-wage markets will put downward wage pressure on other jobs. Extra surpluses will mostly be yielded by financial asset holders.
The solution here is simple, require people pay minimum wage. If you look at corporate profits in the US for example, there are plenty of surpluses available to pay people.
Some jobs will go away, that's fine.
I can't believe what I'm reading on this thread, the only other time I've been suspicious of 'ideological paid bots' is when I see a ton of people defending the CCP.
