An individual can sometimes strike out on their own and succeed, and that's all to the good. But it simply does not scale across every sector of the economy, let alone being a viable strategy for most hand-to-mouth laborers (IIRC, something like 40% of US workers have less than $1000 in savings).

Every shareholder and investor wants a competitive moat: for corporate firms to have enough market power (including lobbying power and regulatory capture) to keep labor costs low (with an intentionally managed reserve pool of the unemployed, via NAIRU, to "discipline labor").

The fact that some individuals can beat the odds, does not change the systems dynamic: "the table is tilted, the game is rigged".
