Unions can be useful or harmful depending on the details, but I genuinely think some kind of collective bargaining is essential to protect society as a whole. Entities with capital want to turn some of that capital into labor in order to generate more capital. Entities who have the supply of labor (populations, or skilled sub-groups) should be able to negotiate as a group if they choose, and get a better deal for themselves while still allowing a profit for the ones with the money. By disallowing the formation of labor unions, we tip the scales in favor of those who already have capital so that returns are maximized and worker gains are minimized. And when the economy grows, the gains go to the top, because workers can't collectively control the labor supply the way other entities control the supply of capital.
