But I think you're trying to connect the dots a bit too hard. First, Trump is not competent enough for the kind of manipulation you're describing.

Second, the power relationship mostly flows the other way - megacorps have more control over the government than the other way around. That's rather the whole point of the current system.

Third, corporations still have checks and balances that work quite well - Nvidia has a board filled with powerful people who aren't likely to stand by and watch the company get hamstrung by the dementia patient in chief.

It's true that their are scenarios in which pressure could be applied, e.g. accept this CEO and the government will allow you to sell to China - but Trump can't make deals like that in a vacuum, he'd get hard pushback from the anti-China hawks in the government.

The idea of an authoritarian president as an all-powerful puppetmaster is a conspiracy fantasy. The reality is that there are all sorts of competing powers acting in their own self-interest. Even the trillionaires don't get what they want all the time, as the case of Musk clearly demonstrates.
