As the weather extremes increase, I think that fewer and fewer people will be able to survive in poverty stricken areas and they'll be pushed into homelessness. I just don't see the US ever really dealing with the situation, plus we're going to keep automating jobs out of existence, so universal basic income is actually needed. My parents generation does not understand the challenges today and they've managed to effectively block changes in government.
In order to help people we need to find ways to drastically cut costs on housing. First start with the land: there's more acres of land in CA than people. the problem is just we're not allowed to build anything, anywhere. Secondly, we need to remove all the regulatory roadblocks that prevent markets from solving the housing crisis. if 3rd world countries can afford to build housing, we should be at least be able to do so as well.
