you probably wouldn't have a fertility crisis is there wasn't a housing shortage in the areas the people need to live to work. if you take home ownership as a status symbol now away and it's a non issue, plus you fix no fault divorce, you'd have higher birth rates. smart people don't want to suffer having kids when they don't have a support network to help them, and being a few paychecks away from homelessness is a detterent. this doesn't affect niggers or muslims, because they just get subsidised accommodation and aren't mentally hampered by hypothetical breakfasts.
