It's the Supreme Court that has expanded the powers of the President, and previously of the Federal government, far beyond what was ever intended.
By allowing the federal government to dominate the states, the Supreme Court created a position of unrivalled power.
Trump may be an evil narcissist by the standards of normal people, but there's plenty of those sorts of people in politics. That's why you have a constitution.
Sort of, but Congress also wrote a bunch of pretty broad, vague laws, delegating a significant amount of power to the executive via agency rulemaking, and it turns out the agencies are part of the executive branch and have to do what the head of the executive branch says they have to do (within the limits of those broad, vague laws). If Congress can't get back to smaller, simpler, more specific laws, and they continue to pass the burden of this complexity over to the executive branch to figure out, the executive branch will continue to wield outsize power.

And it's really fumbling as of now. The tarrifs were 100% on Trump and it's clearly thrown a monkey wrench in everything. the federal judges have slowed everything to a crawl, and these spectacles with immigration have activated American eyes in ways we haven't seen in decades. These kinds of plans work in the shadows and as of now it's all out in the open.
It will reverse in November at this rate, but even a few more reisngations or deaths in the house can dramatically shift plans.
