Food production is the obvious next step to control the population. Small family farm operations are going the way of the dodo. Buy local movement has put a kink in their plans to a small extent though. Golks are waking up to the value of fresh locally grown produce and meat.
I've never been without a large garden, growing up or after leaving the house. We've always bought half a beef and a hog from family or friends and had it butchered. We buy chicken at the store but eggs from the neighbor, and obviously supplement what we don't grow and preserve, but it's a lot less than a lot of folks for sure.
Once they have single payer health care, food will be next. It will be declared that food is a right and it should be provided free to everyone.
