Does anybody else think that unions are really labor side price fixing, and not much different to companies conspiring to fix prices, or the recent tech companies conspiracy to not poach each other's employees (a form of wage fixing, but on the side of capital.) It seems hypocritical to support one and be against the other.

On a less theoretical note, looking at stagnant wages over the last couple decades, it seems clear that between capital and labor, capital seems to hold more bargaining power. So something is needed to tip the power balance towards labor. Whether that's unions or something else, I have no idea.
