> Although there is a lot of capital investment in a job.
No there isn't. You haven't put up any capital when you join a job, and you aren't (generally) required to invest any as you go along. Your time is not capital.
Auto Loans, Student Loans, training, certification, internships, moving costs, and other small costs like special clothing are all investments made by employees to be paid for before or during hiring. In addition, many businesses require employees to buy tools and special equipment like boots and safety vests.
Correct, is way worse. Proletarians don't have any capital to lose. Capitalists do. So if they lose their capital, they can just be like the rest of us. If we (proletarians) lose our job, we risk poverty and death.
