That’s why free market is how we call a market where anti-monopoly laws exist, work and are enforced in full.

While what you are talking about isn’t called market, it’s called jungle.

Self-correction in a market is an illusion crafted people either desperate to salvage a broken system, or those who seek to exploit them.

Self-correction exists when anti-monopoly laws exist, work and are enforced in full. It doesn’t exist when they don’t, because self-correction relies upon competition providing a choice and the consumer using it.

Also trade unions and customer associations are part of what we call free market. Both are voluntary, in public interest, and work when they exist. No coercion involved, thus no violation of market laws.

Also on large enough scale of the market and small enough scale of all businesses it may sometimes seem, that anti-monopoly laws are not needed. Especially since when anti-monopoly laws work, the market appears such.
