Why are so many people Anti-abortion in a country overrun with people?

With over 300 million people in the U. S., shouldn't the government be looking for ways to PURGE the population, not ADD to it? How would the population change if ALL BABIES were aborted for 10 years... no new people being added to the population, while old fux would be dying off!
