Capitalism is slavery

If we do not have our own land then we must have either a boss (someone who buys our labour) or a client to survive... if we do not want to be a thief and break the law. So then those without land must have a boss (a client is also a kind of boss) to survive. We can either have a boss or be a farmer and have land. But the problem with not having land and relying on a boss for survival is that the boss is entirely within their rights to refuse employment. The boss can 'fire' us at any time perfectly legitimately and then we will have no food... so without land to eat requires the consent of another person which can be viewed as slavery. Capitalism is a form of slavery because if we want to eat then we require the consent of another person... they need to purchase our goods since we have no land. If we have our own land we can avoid this problem of capitalism but without land we are always a slave... even if we are able to sell our labour. If our livelihood relies on someone buying our labour then are are slaves. Landless labourers are slaves.
