We're obviously not operating sustainably here, and these R-selection groups (mostly everything that isn't a European, Slavic, Jewish, or Northern Asian) are just cranking out kids like no tomorrow.  If Anonymint wants some type of knowledge age, the K series groups would literally need to wage war on the R groups.  Otherwise, they're just going to keep reproducing until not only are the lower levels of Maslow's pyramid the only things of value, but until everyone literally dies in the process.  Resources are one of the main contributing factors to war after all, but ecological collapse is also not the greatest idea.
