Power perpetuates power
Eric: It isn't if you can't go and work somewhere else.
— J. B. Priestley
Not everyone is in a position to find another job. And what do you do if the best place you can work is still rubbish? What if you're an ISP tech?
Okay, sarcasm aside; I've worked for many different tech companies and good managers are exceptionally rare and there is no pressure from the top to change that, and pressure from the bottom doesn't work. There is, however, a lot of pressure to not fire or demote managers as it looks bad for the management above them.
You can’t get rid of power, just redistribute it. As flawed as democracy is, that’s what it attempts to do.
Or do we want to get rid of governments? ;)
In that case I’ll happily make the same snarky comment about whatever collection of humans accrue and then abuse power in our new government-free society.
People are naturally social. There will always be power, wielded in one way or another. But we have and will figure out schemes to wield it in a to benefit the many more than the few.
I find it fascinating, particularly in a country like America where democracy is a core part of our being.
Unions allow people to vote on their own preferences, then use their collective voice to negotiate. If you don’t like some bullshit union practice, then that is the fault of the people in it not the unions themselves.
