Teachers unions and getting rid of terrible teachers; cops and the drug war - judges too; populist politicians who spew idiocy, racism, and anti-science rhetoric so that they can garner the support from voters who hold similar opinions; the mega-rich in America and issues of fairness/taxes (see: Koch brothers); home contractors and using truly new materials, technology, and ideas to build responsible homes; etc. The further I go in school the more I realize how difficult true change is to accomplish - especially as the area of interest gains prominence. We had a lawyer that specializes in litigating claims related to architecture speak to us. His message over and over was that lawyers and judges, given opposing opportunities, will make legal decisions based on which allows them to stay busy and make more money. It was a way of predicting the outcome of any given trial that proved quite accurate.
So now the constructive part - how do you incentivize people to change their deleterious but self-preserving actions for the benefit of all?
