The end of collective bargaining is the end of the free market.
It's very easy to understand the negative realities of unions, but nobody starts a union for fun. It's risky business. Industries are classically given plenty of chances to adjust. Sometimes they even do. That's why it's called bargaining. Small businesses, products, brands, they all work on this same principle. Go complain to Consumer Reports!
You have explained why the game industry is able to take advantage of people, but nobody asked. It's well obvious. The question is whether you find the behavior acceptable. I cannot relate to punishing people for wanting a career in an $18.4 Billion industry. Maybe it is a privilege. Some would call it the American dream. Many colleges promote these degrees. Maybe that is where you should direct your anger, because the result of corporations exploiting labor is no mystery to history.
