Let's not forget, in percentage terms, immigration rates were much higher a hundred years ago.
-----------

100 years ago immigrants were not pampered like today
so we could afford more

No free English lessons
No free medical
No subsidized daycare
No welfare

No Child tax benefit of over $500 a month per child for family with 8 kids

No affordable housing

Immigrants then plowed the land if they had to'
Today they go on welfare, unemployment etc.
