Traditionally this existed as parents moving in with their adult children. Half of the bargain would be babysitting your grand kids. In exchange you got a roof over your head, food, and the joy of seeing your grandkids on a daily basis.

It does work. Modern society has agreed upon on taxing earned income to provide shared services. That's where the money to pay for all the things you describe comes from. The roads, firemen, police, you name it. It all comes from income taxes (or that and real estate taxes for some of the local stuff but primarily income tax).
By taking care of your grandchildren and generally being helpful to your kids, they're covering you end of all of those as well. They earn the money that buys you food. They earn the money that puts a roof on your head at night. And all that money would be taxed per usual. Arguably you'd be paying more taxes in this setup that if each of you split out and made a more meager existence due to the progressive nature of taxes (i.e. your son making $50K pays more than if each of you made $25K).
