If your swallowing that bullshit, you're not thinking.
Union bombing of non-union construction sites between 1907 and 1911? C'mon.
Union leaders endorsing, and calling for members to vote for, political candidates they feel will benefit the members the most? Well, duh.
Unions have done more for the working people, especially women and minorities, than all the labor laws put together, which would never exist without them.
They have allowed workers to move up to the middle class with the bosses, and curtailed abuse by the robber barons that regulated the workers lives on and off the job. Without, unions and the laws they got passed/enforced, everyone's job, if not life, would be like being in the military.
The benefits of the unions in this country are reaped by everyone even if they've never belonged to a union. Do you think the non-union employers would give you a 40 hr week, your wge scale, or any benefits, if they didn't have to compete with unionized employers for help?
let's get serious here, unions are groups of people, and have all the warts and failings that people do. But the bottom line is they do an order of magnitude more good than harm.
