And likewise, people tend to view other people based on their own culture.
So, yes, there are LOTS of people that would willingly become slaves, of course, people that are NOT from the current caucasian culture, that defends Liberté, Egalité, Fraternité.
I don't want to drag this thread OT, but... seriously. Caucasian or not, the concept of slavery doesn't vary that much from country to country. The consensus opinion is that it is not a positive thing for the world. History has shown us that.
Give me a few examples of people willing to give up their human rights willingly, without external pressure, prejudice, abject poverty or violent coercion driving them to do so. I'm sure there are some willing to do it. But many would probably have some sort of psychiatric disorder. Only a small subset of those have rational and justified reasons for 'giving up' their human rights, not "LOTS".
Despite what ethnic background you come from, basic intuition tells us that slavery is morally not right.
Would you consent to it if you had any other option?
