Because unions are a leveling mechanism, so if you consider yourself an above average, or even average performer there’s a good chance a union is going to leave you worse off. Why would you want to submit your labor to a collective agreement if you think you can do better or at least equal to the rest of the collective? The only thing a union is guaranteed to be is pro-union, not pro-employee and certainly not pro-you-in-particular.
The only time a union definitely makes sense to an existing workforce is if they can suppress labor supply by implementing onerous barriers to entry into the profession, like lawyers, doctors and pilots have.
They can be a force of good for enforcing labor laws. But law enforcement is certainly not a job that should be left to private organisations, that really should be the role of the government. But even then, if you’re earning an SV salary, you absolutely don’t need a union’s help to settle your civil disputes.
