Yeah, every Country had Slavery up until like the late 1800's. What, like 95% of the world stopped? 2025 China still going strong. You want to minimize what they are doing, that's on you.
Do you have a passport and travel around? Look this is not an insult so please don't be offended.
I remember having a conversation with my American buddy who worked in JP Morgan and was posted to Hong Kong a few years back telling me that only around 51% have passports.
The military traveled more have have seen more because of their vocation. Dudes with passports in America mostly travel up north to visit their relatives or goes to Central America or Caribbeans for holidays.
And there will be a bunch that will travel to EU and in the East to Japan or South East Asia mainly to Philippines and Thailand ( You know why

)
But not too many will travel because where you are at is so huge that going from one state to another you will experience a whole new culture.
And what do you define as slavery, the Chinese work for nothing farming in the fields singing songs?
