With all due respect, this is exaggeration at best and untrue at worst. Life is better today for the overwhelming majority of Americans than it was 10 years ago, 20 years ago, 30 years ago and so on. Certainly there are groups of people (I’m thinking of the Rustbelt or southern textile mill towns) that have suffered. You aren’t going to win people to your side by complaining about everything.
Empathy in politics is tricky because it often comes across as insincere. Clinton could do it, Bush could, Obama could. Trump and Hillary wholeheartedly could not. Biden could not. Harris TBD.
