It's been about 100 years of congress abdicating their responsibility and delegating rule-making to agencies under the control of the executive, as well as the federal government coalescing power through the commerce clause and various other means. The US Government was never designed to be this top-heavy, and certainly not designed to allow one branch this much control. Natural consequences of a congress asleep at the wheel. More focused on quick public opinion wins through ham-fisted rules without having to actually write and maintain legislation than reducing the influence and power of the federal government and ceding power back to the states as designed.
