Well at work you are not free to move.
You have to stay exactly where your boss tell you to be.
You don't have the right to express your opinion freely if they contradict the way of the company...
Since 2007 the incomes are growing less than inflation and with a consistend trend, while benefits are steadily growing (thanks to QE).
It prevents you to freely choose your social relationships and mate (social integration) and it takes most of your living in good health life.
Thus I don't know when, but if the trends does not invert, than there is mathematically a point at which we will be paid less than what is required to provide our primary needs, which can be called not being compensated for your labour.
This is already happening for the poorest workers.
So, given that the last point is just a mathematical projection that is bound to happen our system is already "slavery lite" for some of us and the trends is towards a slow contamination of the rests of the workers.
That is for certain.
Knowing when it will be noticeable in your own life is a question of a propagation of a signal to your environment.
Ok, I am pissed at not being able to see the wife I married in order to see her more because of our jobs is making me mad.
I love her, I can't get enough of her, I would like to show her the world and meet interesting people but I am not free.
I have a job. She does have one too. And WE CANNOT FUCKING LIVE HAPPILY EVER AFTER.
A system in which there is no possible nice ending for your life like a fairy tail is not worthy.
I don't intend to give up, though.
