Not even remotely true, Idk how you can say this with a straight face after all we have seen in Trump 1 and Trump 2.

Elected officials are basically the CEOs of each of these agencies, they have massive unilateral control and, apparently, can simply choose to unmake the agency at any point.

Except unlike CEOs, they require regular voter approval or they get punted out. If they make a stink the public hates the next president can easily axe their ass. That alone is infinitely better; how many of these horrible companies have 10-20 year CEOs pushing all this shit?

>drag their CEO into congress.

So they can lie and stick their tongue out for days, or just not show up? There is never any consequence for this, congress is functionally toothless. Only the courts and the executive can actually use punitive action.

The fact that there is an avenue of redress at all for public officials makes them so much more accountable than any corporation. Which is exactly why corporations spend so much money influencing public election and congress, they need to subvert the only system than can keep them in check.
