Depends on the slave, but I call bullshit on "don't have to participate". If I don't participate, in 3-4 months I'd be homeless and with nothing to eat. What gives?

Everyone has choices, it's true.

The choices that are available, however, have an extreme variance from person to person. At the extremely shitty end, Viktor Frankl, while a captive of a Nazi death camp, worked out that when all other choices are taken from a person, the only remaining one is to die with dignity.

But it's a choice, right?

At the other end of the spectrum, choices may include where to vacation this winter or if the maid should be fired.

The bottom line is that the quality and quantity of choices vary so much, depending on luck and pluck, that it's a bit glib to say "everyone has choices", including, I guess, the choice between working a crappy, abusive, mean job or two to make ends meet, or starve.

"It could be worse" fallacy.

I don't think everyone has the luxury to philosophize about giving up material possessions and exiting the rat race, either. A lot of people are living from paycheck to paycheck (or worse), have dependents, and don't have the prospects to find a new job. Those people can't afford to say "no" to their boss' unreasonable demands.
