I can't speak for every American but I find that plenty of Americans are fine with collective bargaining they just don't want to do it through a union if they're in a lucrative line of work already. Which isn't terribly hard to understand, they don't need or want an advocate whose main role is constantly issuing new demands they never cared about on their behalf. They just want to be able to pool their leverage as high value workers within the organization collectively in times of crisis.
