Are "Freelance" websites really freelance???

It doesn't matter how many times you sign up at a freelance site and bid for jobs, because I guess other countries have a totally different idea of what freelance work is. I say that because many of the people posting to do the jobs offered, are not indeed individuals wanting to do some work on their free time, but actual companies from other countries... WHATS UP WITH THAT?
Come on America... you know the problems that all Americans are having and your giving these jobs (our jobs) to them. I'm starting to think American businesses are enjoying are economic downfall.
They just need to keep in mind that because of there actions now, there business will soon follow!
