Capitalism is a system where the people doing the work are not the ones deciding over the fruits of their labor. This decision is instead made by the entity that owns the means of production.
EDIT: WOW what a dishonest way to completely edit your post, and way to escalate this completely. A modern employee is in no way comparable to a slave, especially not the kind of employee likely to visit HN.
What an elitist attitude.
H1B visas are a modern form of forced labor you might be able to find some shred of empathy for, but I kind of doubt it.
The US could do a lot better when it comes to worker rights, don't get me wrong. But comparing a H1B worker to an actual slave has a very misguided vision to what slavery is, and how it continues to impact people around the world today.
The Slave reference is not as inappropriate as you might think. The vast majority of people living in our modern capitalist systems are no more free to chose their employer than a a Slave in ancient societies or a Serf in medieval ones. They are bound by their respective circumstances and have little negotiation power.
I'm happy that you are in a privileged position with more than enough negotiation power. It still doesn't change the fact that you don't get to enjoy the fruits of your labor, but you are left to enjoy some of the fruits of your labor by your employer.
I'm curious; why do you think that there's a "capitalist" - that has enough resources to build a factory and buy the machines and the tools - and "laborers" in the first place?
