This is why we have trump. Biden hasn't been a great president, he has had a great presidency. The man who is president is a small part of the equation. By attributing it all to him instead of all the people in the administration, in congress, and to just to where the world was at the time, we reinforce a culture where people praise guys like trump, and musk, and other billionaires. All of them were mostly lucky. They had some special skills to take advantage of thier luck that others don't, but without the luck, they would be nobody.
Stop praising people for the work of many and good luck.
The ability to select a competent, effective cabinet is a quality of an excellent leader. In a simplistic sports analogy, being a star captain and team manager doesn't mean you score well on your own.
Trump had one single curveball thrown at him in 4 years which was the COVID-19 pandemic, and his ilk of sycophants and him couldn't get an effective national response and the competent people like Dr. Fauci were ridiculed.
In the various conflicts that have manifested in Biden's term, we can be confident that the people in charge of the respective office under Biden's command aren't there just to make money off of each crisis.
One can only select from what is available. And that is where the luck comes in. But they barely select the cabinet, thier staff do all the work, they just have to pick from a short list that the current political climate provide as possible options (congress has to approve them). Their primary staff are either people who joined on long ago, or just the people the party has deemed are having the most success.
And while you think trump's administration was ineffective, that is only true in the sense that he didn't do what you wanted. From the conservative point of view, he knocked it out of the park. His administration used the pandemic to further drive the voters to extremes, which his party needs to gain power. The supreme court (also mostly luck). The plethora of conservative federal judges. The rich got richer and the poor got poorer. The list goes own.
