What is not achievable? We're talking about collective bargaining, how is that not achievable without outside help and involving the government? People got it working just fine 100 years ago... Of course back then laws were not favoring corporations that much (in my country where it worked then, not the USA).

Getting collective bargaining started requires assembling the collective - this is a lot harder to do if the employer can just fire anyone seen organising.

Traditionally bootstrapping into a situation where union organising could happen safely and peacefully required a period of violence on the picket lines. There used to be quite a lot of this in America: https://en.wikipedia.org/wiki/History_of_union_busting_in_th...

These days it's even harder in some ways; the more "virtual" an organisation is, the easier it is for the company to just disband and restart it and the harder it is to picket. It's not clear if the various strikes against Uber by its workers have achieved anything.
