This is an adversarial process. Unions exist to fight employers. Unions spend about 23 billion a year in total. Only spending 1.5B to defend against 23B looks like a bargain.
A way to exit the adversarial process is by ending the separation between owners and workers, through things like worker cooperatives, employee ownership, and workplace democracy.
AFAIK The USA is one of the most anti-union non-authoritarian countries for a very long time. In other countries people receive a lot more support and protections for the right to organize
It that’s true, why is union membership declining? why did Trump et al gut the NLRB? why do starbucks unionized employees STILL not have a contract years after forming a union?
