Here’s a fundamental question…
Where in the Constitution is the Executive Branch - or any Branch - explicitly empower to “bust trusts?”
Here’s a hint…it’s not.
Well there’s a whole lot of stuff going on not in the Constitution. Some monopolies have been broken up in the past. Standard Oil and ATT come to mind. Not sure what they plan to do to Apple though.
The SCOTUS found it in two 1937 cases that the Preamble’s “Promote the General Welfare phrase” allowed the Constitution with Congressional Acts with the Presidential approval to do almost anything that “promoted the general welfare.” Once that horse was out of the stall and escaped the barn, everything “promoted the general welfare” including anything an imaginative leftist could come up with that benefited anyone any where or the government or the state, or an imaginary benefit could be justified. It first of all found that Social Security taxes and payments promoted the general welfare.
