There’s a big difference between “I don’t like my job, I can’t quit because I need money” and being a slave.
A slave, who has no rights, legally and socially, who can’t vote, who isn’t paid, who is bought and sold like property, with no standardized working day, hours, vacation, health insurance, not even the ability to have kids, family, marriage on their own terms, no retirement, no social security, no unemployment, no ability to own their own property, bank accounts, credit accounts, no education, no higher education, no ability keep their own culture or faith, or leave if they don’t want to be there…
Let me cover those points:
1. not all types of slaves can be bought and sold.
2. many types of employees do not have standardized working hours or days.
3. Many simply can not afford to take vacations they are entitled to.
3. Many people working multiple part time jobs have no health insurance. Regarding the ability to have kids, the only people that don't are those that are either sterile, or really, really ugly.
4. Many "free" people do not feel they can have kids or a family because they can't afford it and they are too busy trying to make rent.
5. A LOT of people have no retirement
6. Unemployment and social security are a new thing, and not universally available. They are also government provided. i.e. outside the scope of this discussion.
7. Many poor people have no bank account. In fact, it can be harder today than it was 20 years ago. Same for credit accounts.
8. Regarding education, I return to number one above. Not all slaves live under the same conditions - just like employees.
9. Regarding faith, I will give you that one, but with a caveat: When I worked in Seattle, mere mention of my Christian faith could have gotten me fired. Yet when I moved to Kentucky, we had a pizza day at my new job and before we cracked the boxes open, the boss prayed over the meal.
10. I addressed that one in my post before. Employees "technically" can leave, but often times don't "think" they can. And it can be for a myriad of reasons. In my job they called it "golden handcuffs". And what it really means is not that you are rich. It means you make a very good income, but have amassed so much debt for the car, the boat, the McMansion that you CAN'T quit because those kinds of jobs don't grow on trees. So you stay stuck as a ever fattening cubicle rat, quite literally with a "slave" attitude, afraid to say or do anything that might tick people off.
Again, I'm not saying being an employee is EXACTLY like slavery. I'm really saying it is one of the "softer" forms of slavery. After all, nobody is truly a slave to another person unless you don't have the ability to unalive yourself. It's why it is said to not fear him who can kill the body, but fear him who can kill both the body and soul...
Something I've said for well over a decade regarding the US education system: Public schools are a 19th century paradigm that outlived its usefulness in the early 21st century. Their primary purpose today is to supply free daycare for parents that have sold themselves into indentured slavery.
