Unions are not terribly interested in overall productivity/output. Their goal is to maximize the value to their constituents (either through wages or working conditions). By decreasing/holding stagnant the supply of labor available, they are able to force wages to be higher than they should be. Of course, as economists understand, this causes all sorts of problems. Unions really aren't that different from corporate lobbyists... What's more impressive I think is how vehemently anti-immigration (and to your point, anti-black at various times) the Democratic party has historically been (mostly driven by union influence) and how quickly that seems to have been forgotten by most.
