Modern slavery does exist as many have already pointed out.
I had relatives who worked 12 hours a day, 6 days a week for a 300 dollars salary.
In my country, that's barely enough to rent something 1 hour and a half away from your working place and to eat something every day.
Get yourself out of your very own world, your cosmovision, and imagine that you don't know people in a position to help you or that you don't have the means to be economically independent. No special technical knowledge, no tools, no house, no money. Just the urge to have something to add to your family table every day. You think about it every day but there are only obstacles everywhere (people tend to think that poor people and because they are lazy or stupid and that poor countries are poor because they are the land of ignorant people ruled by corrupt men, and that's a very coward and condecendent way of thinking).
Those who have lots of money in countries as mine, who are very little people and are very very rich, can easily hire lots of people in great need. They can pay very low salaries and most of the time they pay what we call black salaries (no legal salaries). That means no protection at all in case of trial. That means you as a worker are totally screwed. International companies pressed local legislation to become more "flexible" in order to make of those countries "echonomically viable".
Those people (and those companies) get richer and richer because they practise modern slavery. And they think the OP idea is not so brillant nor new because slavery has not stopped happening, ever. It just changed its name for modern audiences preferences.
