I refuse to follow this logic, because if I did, I would have to accept the fact I don't have any autenticity or free will at all, since it's all about a gray undefined body called system which decides everything for me.
This system is composed by people like us, who somehow managed to accumulate power, using their skills and cognitive abilities to manipulate and take advantage from average citizens of society.
They are constantly trying to make us to believe we have no choices, besides playing their game. The fact you are persuaded to always choose the lesser evil is an evidence of that. However, you don't have to. You always have the possibility and potential to find gaps on this system imposed to you in order to thrive and develop yourself, despite obstacles and sabotages.
The difficult level involved in not playing the system's game may be high, but it's not impossible, and I guess the purpose of life is to not give up to them. Key point I've found is to be less dependant as possible on mainstream groups, while becoming more autonomous and self-reliable on yourself.
And you would be right to decline that idea. There is absolutely no "slavery" in what we do, it's obviously not a great life to live when there are so many things that we can't afford, but being upset that you can't get what you want, doesn't mean we are slaves. And just because business owners could make so much more than the worker, doesn't mean they are masters.
We can easily quit any job we have, that is the proof that we are not slaves, there is absolutely no other reason required, if you can go to work today, and give your two week notice, that means you are not a slave. Slavery has to be being hold against your wishes and that does exist in some sweatshop parts of the world, just not around where we live. I believe in the power of individual, and the right to be as strong as possible, so many people grew up from nothing and even became presidents, and that means we need to realize things aren't going to be that bad for the individual at all.
