Wrong!
Third World migrants take more from the system than they put in. England is full of large Muslim families entirely on the dole. Ditto Sweden, Germany, etc.
Furthermore, a large percentage of Third World migrants are anti-white racists. Do you think a few decades from now, when they're the majority, they'll happily financially support a large population of elderly whites?
A shrinking population is not suicide. You can cut back on benefits. But importing large numbers of violent thugs demanding handouts and reparations only makes things worse.
You don’t have to have a shrinking population. What needs to happen is for extended families to be encouraged now, so that we don’t get in the same pickle as Japan (that is trying to pay young couples to move into aging communities or to move out of Tokyo). Extended families are a cheap way (tax dollar wise) to help address both the lack of affordable daycare as well as eldercare. It literally is the most fiscally conservative, as well as traditional values conservative solution. How many more babies do you think people will have when they no longer have to pay $300 a week in daycare per child?
