That's true to an extent, but unfortunately unions (at least in the US) tend to end up mimicking the same corporate behavior they are supposed to be placing a check on. The get bigger and more powerful and they start to take and take with no concern for the fallout, and like corporations, they get politicians to do their bidding at the expense of the general population. There are towns near me teetering on bankruptcy, while the police and firefighters can retire after 20 years of service with a pension equal to 80% of their last 3 years of pay. Any effort to reform what is obviously an unsustainable agreement that never should have been struck in the first place is meet with a wall of resistance and veiled threats to public safety. In the private sector, unions have had a long history of opposing environmental regulations out of fear that it would affect employment in heavy manufacturing. Auto workers unions have repeatedly opposed any effort to invest in public transportation and reduce auto dependency. I've heard that Scandinavia has had better luck with unions, but here in the U.S. unions have been every bit as self-serving and bullying as the corporate overloads they're supposedly a counter balance to. I'd love to see better restraints on corporate power, but I'm not holding my breath for unions to be anything but one more moneyed interest.
