Totally true.

Nothing forces companies to treat workers well

Because the power of workers (via unions or simply a fair job market or labor regulations) has been systematically attacked since forever, because that is in the self-interest of corporations and their owners.

As corpos and rich fucks amass more power, it is easier for them to take power from workers. They can more easily crush existing unions and attempts at unionizing, change or hobble labor laws, meddle with the job market itself, and influence the government's management of the economy.

So the trend is towards overpowered corporations and underpowered workers. We get to a point where workers don't really have many options for better jobs, and they don't have enough sway to raise the minimum wage for decades, let alone attain a more fair job market. Or implement regulations requiring better treatment.

That's in addition to seeking ways to replace workers with technology, or increase their productivity.

Thing is, if most of us are unemployed because of automation, who's buying the products and services enough to sustain these companies?
