> But we all know those shareholders would quickly fall into poverty if their returns reduced.
That isn't true. Investors will simply move their capital over to other things with better returns. So restaurants will simply close down if they aren't worth running and no one is going to fund them.
> Equally if that’s not possible, the company should fold. We shouldn’t prop up companies with cheap labor, that’s just forcing the poorest in society to provide corporate well fare, and basically the same excuse that was given for preventing the abolishment of slavery.
That is the likely result. Or the companies will invest in automation to make (automated) labor costs predictable. More likely, services that are easier to automate will survive while those that aren't will not.
