The problem with owning slaves in 1.0 is that if they got sick or died, you lost a valuable asset. The aim now is to create a large, impoverished class of people that work for very little money and get no real benefits or health care. But, when they get sick or can't work — You just toss 'em out and get some fresh ones.
In slavery 2.0, Workers are just disposable commodities. While they are technically free — They are so controlled by debt that everyone of working age in the family works multiple jobs just to stay alive. They have no real opportunity for advancement.
In the end, this is cheaper for the businesses.
