Your causality is wrong. This adminstration has no interest in working with competent people. They're fired huge numbers of them, gone out of their way to make life hell for those left so they quit, and are moving faster than ever imagined possible to drive competent people in non-government jobs away from this country - by deporting them, taking away their visas, attacking them, and more.
I disagree. The first Trump administration showed that not only were some competent people interested in working in the Trump cabinet, plenty of other competent people were content to keep doing their non-political jobs well for the government, running things, fighting for normal people and what they right, pushing back against overreach.
The second Trump administration took aggressive measures against all competent people - selecting a horrifying cabinet with literally no one qualified for the role they fill and working as fast as possible to fire as many as possible, even through illegal means later rejected by the courts, and punishing any who remain. It's a one-direction causation.
This administration is a haven for charalatans and grifters. It's no surprise that they don't have competent people. The goals of competent people are diametrically opposed to what this government wants to do.
For example, most competent people I know didn't want a nuclear war to start yesterday. Lo and behold, the administration also did not start nuclear war yesterday.
While there are a lot of incompetent idiots in this admin, don't forget that a lot of them are grifters who are only trying to get rich/powerful while they can.
I don't like doing the Hitler comparison, but the similarities are definitely there. A lot of the Nazis thought Hitler was a "useful idiot" that they could use and then get rid of. Trump is very similar.
I would imagine this is true of many other dictators and authoritarians over time too: Putin, Kim Jong Un, etc. If you are looking for non-Hitler comparisons.
Jokes aside, it's really sad to see seemingly no competent people not wanting to work with this administration.
