>New members reduce the wages if existing ones.
no they don't. one of the most basic things almost every union does is standardize wages.
>Also competing firms are also a threat.
this is why in fields that actually matter, unions form larger bands of organizations across the entire field. and ideally, a place being unionized and thus having higher wages, better bennies, etc. would make it more attractive to workers, increasing "competition" i.e. securing access to higher quality applicants. when a union functions correctly among the trades, it becomes more of a guild
>Also unions raise prices on consumer goods the working class buys.
wages are among the smallest parts of overhead in the actual cost of a modern consoomer good. that 2100$ macbook didn't cost 2000$ of man-hours to make. and margins are not so slim that the consoomer price can't stay stable
>Why would they intentionally destroy their workforce and have to spend a bunch of money to hire again?
watched too many episodes of "dirty jobs" before going on LinkedIn
