"We", are the capitalists. Those who own the means of production, and use that "property" to have others work for them. They're the owners of factories, and have workers make products for them. They're the owners of land and housing, and have the tenants pay for the privilege of living there —effectively, tenants partially work for their landlord.
Interestingly, becoming a capitalist is almost as difficult as becoming nobility used to be. It's not a birth right, but very few people manage to start poor and die wealthy. Even creating your own personal business is not easy —though some professions, like medicine, have it easier than others. Capitalists are a caste.
So, what to do when you're not a capitalist? The only thing you can reasonably do: you go find an employer, and give up most of your autonomy for 40 hours a week. Well, given the sheer amount of part time work we have in our industrialised countries (including France, Germany, and the US), it's more like 30. 30 hours a week, you have basically no say in what you do nor how you do it. You can only hope that whatever is being asked of you resembles what you actually want to do. For most people, this is not the case: they just hate their job, but live with it because it's the only way they can pay their bills. (And no, they don't have access to better jobs. And switching jobs is a pain. And they have a poor bargaining position in the first place, thanks to unemployment.)
That was an individual's point of view. Collectively, things are much worse. See, a small proportion of the population (the capitalists) can decide what is being done. They decide what has economic value, provided they can sell it. When they can't sell it, they use aggressive marketing (fashion) or artificial scarcity (copyright) to sell it anyway. They lobby for laws meant to reinforce their position (as is natural: when life is good for you, you want it to stay that way), effectively preventing the common people from having any serious say. And of course, there's the maximisation of profit, that have the capitalists drive wages down, or maximise production, or outsource work, or externalise costs… or all at the same time. They destroy people's lives (outsourcing) and pollute the land (externalisation). It looks like long term, capitalists are at best poor decision makers, and at worst criminals deserving the chopping block (or anything that permanently prevents them from doing further harm).
Lucrative property is currently human right. Probably the most fiercely enforced. It should be abolished. No one should be able to have others work for them just because they happen to own something they don't use themselves (land, factories, houses…). I'm not sure what the alternatives are yet, but capitalism just doesn't work.
