that's just dumb.
first of all, if the exploited had better alternatives, they would take them. they don't. they need the west to go there and create jobs for them.
second, those governments could regulate a minimum wage, a top number of worked hours per week, etc. they don't. it's they versus they.
regarding migration, the problem is that most of it is illegal, you get murderers and rapists and pedophiles and drug dealers and muslims and blacks and browns.
there are no background checks.
there is no rhyme nor reason to it.
we can just look at failed countries regarding migration, france, sweden, germany, uk, etc.
