This is very close to saying you wouldn't be against slavery. A slave could be given a decent quality of life. Does that mean slavery is acceptable? A person with 50 bazillion will be able to make you a slave if he wants to.
Slaves are free to think that slavery isn't acceptable. Always have been.
Oh, sure, you aren't a slave. You can't be bought and sold like property. But try going a few months without a paycheck and tell me how that goes. And if you happened to get lucky at some point and escaped wage slavery - you have to be cognizant of the fact that most didn't, and never will, by design.
Modern wage slavery vs whatever they had in Mesopotamia is just details of the perks that the owners decide to hand out.
