There are a lot more broken cost structures - housing, which has similar potential losses to incarceration with the stress of rent driving drug use and homelessness costing a ton and taking potentially productive people out of the economy.

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.
