An office of heat, Phoenix

Phoenix had over 600 excess deaths last summer.

At present levels of heating, many of these deaths can be prevented, but that depends on willingness to spend money to protect the health of poor people — often homeless people. Plutocrats consider that a waste of money that could instead be increasing their investments.

It may also depend on whether workplaces are willing to permit precautions to be taken. The Republicans that control Florida oppose that.
