Everywhere you will find that the wealth of the wealthy springs from the poverty of the poor. - Pyotr Kropotkin

Because, to do manual work now, means in reality to shut yourself up for ten or twelve hours a day in an unhealthy workshop, and to remain chained to the same task for twenty or thirty years, and maybe for your whole life.
It means to be doomed to a paltry wage, to the uncertainty of the morrow, to want of work, often to destitution, more often than not to death in a hospital, after having worked forty years to feed, clothe, amuse, and instruct others than yourself and your children.
It means to bear the stamp of inferiority all your life; because, whatever the politicians tell us, the manual worker is always considered inferior to the brain worker, and the one who has toiled ten hours in a workshop has not the time, and still less the means, to give himself the high delights of science and art, nor even to prepare himself to appreciate them; he must be content with the crumbs from the table of privileged persons.

Don’t compete! — competition is always injurious to the species, and you have plenty of resources to avoid it!

By admitting that the only guarantee not to be robbed of the fruits of your labour is to possess the instruments of labour - which is true - the economists only prove that man really produces most when he works in freedom, when he has a certain choice in his occupations, when he has no overseer to impede him, and lastly, when he sees his work bringing in a profit to him and to others who work like him, but bringing in little to idlers. Nothing else can be deducted from their argumentation and this is what we maintain ourselves.
