Transportation and infrastructure are broken requiring private car ownership and whose design holds back community and local growth around the country (in transit and in broken water, electric, and internet monopolies).
Agriculture is also super broken with subsidies for unhealthy corn syrup, half of food wasted, huge meat subsidies, an industry dependent on undocumented labor, etc.
Really they all come back to planned bad incentives - housing is regulated to be cost prohitive and NIMBYed, all infrastructure is deeply controlled to protect encumbant oligarchs, prison industrial complex is lobbied by the prison supply chain and police forces. It all comes back to politicians acting in the interest of few over the many contextualized over many circumstances. And that can only happen if they are unaccountable, which is the root problem to fix.
I guess they could be saying that among the remaining third of the population, the Californians are still unhealthy even if not overweight while the French are healthy. Seems unlikely to be true, though.
Even if you qualify, there is limit to how total many section 8s are given out. So there is a waiting list of several years, during which time you must still qualify.
You can not just sign up on that waiting list. There are small windows open at random a few days a year when they will accept names.
No leasor is required to accept section 8 people and very few do. So even if you get a section 8 voucher, you still need a lot of luck to find a place.
Thus the streets are paved with homeless.
Cost structure of college
Cost structure of healthcare
Mass incarceration (actual cost + lost GDP etc.)
If we fixed those 3, or at least dramatically reduced their impact, we would unlock 30+ years of growth. Its basically free money, just sitting there, waiting for someone to restructure each of them.
