Similarly, I recall a leading figure in the last Trump administration stating that concerns about the impact of global heating on coastal cities were wildly overstated as people just needed to sell up and move inland. The denialism, ignorance and stupidity on display was simply breathtaking!

Seems pretty on par with how humanity has dealt with socialized risks: unless it affects me (or my immediate family) in a very short period of time, I will not give it any consideration or go to the hassle of appearing to care (herd approach). Discount to easiest option of "no change/stay put".
