The root of the problem is the authoritarian structure of modern enterprise. I know many good people who work at bad companies, who, were they given the chance to have their say, would change things wildly for the better.
You'd rather say that at-will employment and especially the tight labour market outside tech enables the authoritarian structure of the modern workplace.
A democracy cannot function when it harbors inside itself a system in which the survival of most people is determined by something organized like a dictatorship. The poor conditions in the modern labor market have been engineered by these authoritarian systems in collusion with the governments they corrupt with their outsized wealth and power. It's intended to disenfranchise people politically and economically to ensure a small class of oligarchs maintains control of both systems.
