(White Birth Suppression and Replacement)
Most of the problem of white birth suppression (genocide) is caused by taxation to redistribute to the lower class, taxation to redistribute to older folks still capable of working even if only marginally, and most importantly, the cost of housing that allows them to economically segregate from undesirables, and the cost of interest on homes that should be effectively zero, since it is just capital creation.
All of those problems are fixable. Easily. By separation.
