Re: slavery always was the condition of 99%+ of the worlds society and even elites
Way to start the year! 
We can argue that the rat race these days is similar to slavery but I personally think it's more similar to serfdom. You have rights (albeit not much) and you can buy off your freedom OR you can flee.
A medieval serf can flee to a town and stay there for a year and a day and he's free. A modern salaryman can cut his expenses for a few years and leave the rat race to be more financially independent. The modern man have a bit more options.
