Whites aren't killing their children, at least not in numbers enough to explain the decline - it's responsible, thinking white couples deciding to have fewer or no children because of the expense of properly raising them in today's America, and every time taxes are raised to support the spawn of brood mares from the welfare/illegal class, more of those white couples are forced to decide to limit the number of children they will have because of the lesser amount of financial resources they'll have available to properly raise them.
I have six brothers and sisters, all near the end of, or past the child-bearing years - between all of us we have 11 kids. All have been very well cared for, and very well raised, because the limited resources available to us to raise them determined the number of children we brought into the world.
Contrast that to those "americans of the future" - their thoughts on bringing a child into the world run along the lines of "it's going to feel good tappin' that ho", "i'z gonna take care of my man tonite", and "hey baby daddy, I needs mo welfare, come on over and knock me up tonite".
Like just about every problem facing this nation, the demographic time bomb is a gov't created problem... the decision by ded kennedy to import the turd-world, the crushing tax burden on responsible parents, social welfare programs that reward and encourage irresponsible breeding, etc.
“Whites” also are not having more children because of the tax burden imposed by the government to pay other women for having illegitimate children.
Consumerism also plays into the mix, but the tax burden is horrendous. And it’s not an accident.
You and your brothers and sisters use the pill?
