(From the beginning, starting over 40 years ago, "trickle down" was just a con. Since it went into effect, the rich have gotten much richer while the poor have gotten poorer.)

Hopefully, the 2017 tax bill passed by former President Trump and the Republican-run Congress served as a kind of last hurrah for trickle-down economics as unquestioned dogma.

Through decades of leadership by both political parties, conventional wisdom uncritically accepted the concept that handing money to the wealthiest Americans in the form of tax cuts and deregulation would eventually trickle down to everyone else.

Trump's tax cuts represented the purest form of trickle-down that had ever passed in Washington, DC. It handed hundreds of billions of dollars in tax cuts to America's wealthiest people and corporations under the flimsy premise that these economic benefits would somehow translate to economic benefits for everyone else.
