We’ve known for ages that paying for social services, healthcare and unemployment benefits increase the amount of spendable income the working class has and that this directly benefits the real economy while more income to top earners only means that that money is lost to the economy.

Most of the problems the US is facing could be fixed, or at least alleviated with social democratic programs. Better economy, better education, less crime, less partisanship, less drug abuse, less violence, less stress, less fear, better mental health, better physical health, less homelessness, more gender equality, more racial equality, more job security, better wages, better lifestyle, more happiness, less religion, etc. etc.
