The branches were not supposed to be equal. According to the Federalist, Congress had “will,” the executive “force,” and the judiciary “judgment.” That’s highly simplified, but Congress was supposed to have the leading role in setting policy.
? Only if you consider "equal" to mean "the same powers"...but the idea of checks and balances is so closely akin to the idea that we can think of the founders' ideal to be equal.
You are absolutely correct that Congress is to have ALL legislative power.
I am very concerned that the fourth branch of government, the bureaucracy, is unaccountable to the people or the Congress.
