Decreasing life expectancy
Due to the expensive and inferior US medical system, life expectancy
for non-college-graduates has decreased every year since 2010.
That's because their income has decreased. As often happens, lower
life expectancy measures poverty. It is understandable that they are
dissatisfied and want a change.
Those who think of addressing this by voting for the Republican Party,
which wants to make the medical system even worse and block's Biden's
efforts to improve it, are being self-destructively foolish.
