Of course they do. And yet these countries do not experience a similar humongous economic disparity as the US.
America used to have that, too. Used to. What changed since then ?
blink, blink and the US, the largest consumer market across the board, is not a *gigantic *free trade zone for its member states ? Not to mention the South American market, which y’all have largely to yourselves.
Precisely. Which means that, quite demonstrably, you can in fact force companies to hire people at the rates YOU think they’re worth.
Not if they concurrently underpay for their lowest. Which is what’s happening, apparently. Not to mention of course that mere price of goods/services is hardly the only (or even the most important) factor in market penetration.
Hell, some business models & sectors actually *rely *on inflated prices. The “high fidelity audio cable” racket, for example - many, many people subscribe to the idea that “you get what you pay for” applies at both ends. I believe P.T. Barnum published birthrate statistics about them 
That truism becomes largely borked when the someone paying you for it and assessing your labour’s worth also happens to be you.
And those other ways could be regulated in turn, making it progressively harder to dance around the law (and avoid the expected results). See: the tax system.
ETA: you might as well be saying that the minimum wage is pointless since “the people who are perceived to be worth less than the cap, their employers will find other ways to compensate them less”. I don’t really see that happening. Well, not to legal citizens anyway.
As I said, the company money has to end up somewhere. You don’t think they’d just accumulate it only to let it sit around and get taxed, do you ? Not that there’d be anything wrong with that…
If the newfound profit turns into higher wages for the employees, I’m fine with that. If it leads the company to expand its operations and hire more employees, that’s good too (the resulting scarcity of the labour market will likely lead to higher salaries in turn anyway). If it’s invested, then someone will benefit from that investment to create or expand their own business. If the money goes into modernization and infrastructure or consulting, someone gets paid for that too. And so on.
