Americans do not carry the immigrants, except for the Muslim” refugees” that Obama is bringing in by the thousands, who go directly onto some form of relief. If we didn’t have the other immigrants who come here to work, many of our states would have a negative birthrate ( more deaths than births ) and we would have not only too few young workers but not enough consumers.
The native birthrate is way too low.
But don’t worry. Planned Parenthood is spending a fortune promoting abortion and birth control among Hispanics and pretty soon their birthrate and attitude towards children will be as bad as that of Anglo Americans.
I would say the native birth-rate is low because of taxation carrying the immigrants of all types via all the programs they can sign up for and the bureaucracy that entails.
