> As unions mature they protect the employment of their members, not prospective members who are unemployed applying for jobs.
This is true in the same way that it’s true that all democracies turn into the majority oppressing everyone else, or get captured by oligarchs, or vote to raise taxes to fund social until the economy collapses, etc. – which is to say not at all. Unions CAN fail that way but it’s not a given. We shouldn’t give up on a useful tool because it can be failed, we should talk about how to keep it healthy.
For example, I’ve seen the no-degree route you talk about made easier by unions because it forced merit hiring rather than hiring more dudes with social ties from certain colleges. Again, that’s not guaranteed – you’d be forgiven for wondering if the Teamsters were a deep cover operation to discredit the concept of unions – but social institutions aren’t magic: they work to the extent that we make them work.
