You sound like one of those doomsayers that always says that if we do anything for the workers, community or the environment like health and safety, working hours, overtime pay, minimum wage, vacation, sick leave, notice periods, regulations, taxes and so on the capitalists will always move to some third world hellhole that has none of these things. The economy would collapse, the jobs would disappear and we'd end up a third world country. So the solution is instead of fighting the race to the bottom or even trying to go uphill and fail, we should just race towards the bottom to get there first. You should probably get rid of the 13th amendment too as long as the slave contracts were entered into willingly.
Once employees are totally free from all protection from abuse they'll be much equipped to negotiate a fair deal with the megacorporations that they seek employment at since it's all voluntary and nobody's going to be forced into anything because they got rent to pay, kids to feed or something like that. Or if they do, it's their own choice/fault so we shouldn't intervene. If the corporations put abusive terms in their employment contracts, people will simply refuse to work for them and another company that hires better people from the full pool will take over, run the other company into bankruptcy and the invisible hand of the market will fix everything. It's almost like Santa Claus, except more adults believe in it.
Maybe it works for you if you're well above average good and it's not a matter of whether you'd be employed or not, it's only a matter of shopping around for the highest bidder. When it's a worker's market and companies are struggling to find enough qualified workers, all is well. It's when it's an employer's market that the thumbscrews come out and people are caught in a game of chicken, accept less favorable work conditions or be out of a job. Oh and almost everyone is now in a hiring freeze, unless you're the CEO's nephew. So would you voluntarily like to sign this revised employee agreement or would you like to voluntarily pick up your two weeks pay check and be on the dole?
Businesses operate on those terms we allow them to operate, sure they can choose not to do business here then but as long as we can find enough jobs that do want to treat their employees decently it's not necessary to bend over and lube up so they'll set up sweatshops here. P.S. Unlike the US, in Switzerland the democracy is not defective. The people actually make the decisions, much to the frustration of both corporations and politicians alike. I consider their model a fantastic democratic achievement that I wish more countries would adopt, but much like the US "two-party" system it'd require the politicians in power to rescind power. That's not going to happen without a revolution.
