If I have one sociological curiosity is this: how much better (in pure KPIs) an organization/society would be if its leaders would be randomly cut from power, sine ira, studio, vel ratio [4]. Given a wide and deep enough structure of power, the individual good (in an extra-moral sense) has a diminishing impact, while the individual bad gets only amplified as power increases. The meta-principles of the structure ought to control this asymmetry and random selection/culling seems, weirdly enough, the most fair, perhaps even the most efficient.

The current bar is so low, so artificially kept low (just on one dimension, around 800 millions of people are starving [1] while around 1 billion are obese [2]), almost anything would be an improvement, especially dispersing power through randomness.

Unions are an idea to counter the power imbalance against the company. It turns it from many->1 to many->many. Now all of a sudden lots of things are negotiable, like different contract terms, which were off the table before.
Altruism is about giving things away. If you want to donate to charity, fine, if you're at the union for charity you're misunderstanding things.
Altruism is about the concern for the welfare and happiness of others. It's particularly important in organizations that fight, both figuratively and literally. An army that runs out of altruism collapses, because people generally don't want to die for no reason.
Look at that dumbass alphabet worker's union for example. They offered nothing to workers for joining, all their goals were social justice culture war stuff.
How are they doing? If they called for a strike, would anyone notice?
