Between the ACA, Medicare expansions, pre-existing condition coverage requirements, VA funding, and medication price reduction, Democrats have ensured that tens of millions of Americans have healthcare. Republicans have done their best to strip this away.
Democrat states usually do not have "right to work" laws that weaken union membership. 
Democrats heavily pushed for a move away from fossil fuels, subsidized the expansion of electric car use, increased protected lands, and strengthened environmental laws. Republicans have undone most of this.
Democratic support of Israel is rapidly waning under public pressure. Republicans have not weakened their stance an inch.
Democrats funded and supported international aid across the world to generate soft power. Republicans have pulled this back and replaced it with threats and military force.
Dems are not perfect, but they are closer to your ideal by an immense amount.
