Belief systems have consequences. Period.

If you believe that what is wrong for others is right for you (subjective morality), you can find ways to do whatever you want to do irrespective of the negative consequences to others.

Combine this with the idea that people are born poor / disadvantaged because of their sins from the previous birth and now you can justify anything you do to them - including making them work in slave-like conditions.

These types of thinking has consequences that you cannot simply wish away.
