Glad you asked.
As I posted earlier in this thread, impose a windfall profits tax on companies that are gouging consumers, such as Kroger's. They've made so much in profits, they're buying the Albertsons chain, which will reduce competition and allow more gouging. Not that I'll miss Albertsons. They're a poorly run company and Kroger's is a well run company, and where I do most of my grocery shopping. But their control of the market is becoming a monopoly.
Housing. It's probably time for government subsidized high rise apartment buildings. They were known as "the projects" in the '60s, but that was at a time when housing was still affordable and it was just welfare recipients who lived in the projects. These days, the working poor can't afford a place to live. Maybe it's time to reconsider high rise affordable housing.
Another action the government can take is to stop Wall St. from buying up real estate and making the situation worse.
What else... I mentioned AI and robotics in my earlier post. That is going to be a major problem in the near future. A lot of jobs, perhaps as high as 25% or even more, are going to be lost to those technologies over the next decade. There's no stopping it. Elon Musk and others have suggested a minimum income to prevent people from starving to death. That may help people survive, but individuals are going to lose their purpose in life. I have no idea what a solution will be for that. It ain't gonna be pretty.
Feel free to rebut.
