I realize that your question is rhetorical, but I'm not sure the facts supports your point. Democrats controlled both the House and Senate from 2009-2011 and controlled the Senate all the way up through 2015. All the while controlling the Presidency as well.
And yet Republicans controlled the White House, Senate, House, and the Courts from 2016-2018 and only managed to pass a $1 trillion taxpayer-funded giveaway to the largest corporations and a few rule changes to make it easier to dump toxic waste into drinking water.
