On second thought, this is a surprisingly interesting question. Here's my take on it:

First I think that people in such positions quickly loose the respect for confidentiality. They keep reading stacks of papers every day, most of which is highly confidential. If we hold an envelope with top secret markings in our hands, we probably would be excited. For them it's just paper. I doubt they read much that does not carry a red stamp on it.

Next there is a common misconception in American politics regarding secrets and confidentiality. In operational security, the principle of least trust is necessary. Whatever is being said in the oval office should be confidential, because you can't perform continuous risk analysis' and individually decide what should be kept from prying ears.

The problem is that on the other hand most of what is commonly treated as secret should be public knowledge. The secrecy of US politics and institutional operations is so pervasive that there is effectively no oversight or accountability while on the other hand the people have no privacy at all.

I can imagine, that as a president, vice-president or ex-president, you have little respect for confidential documents. However, I don't think that what we see with Biden is actually the same thing as what we saw Trump doing. From the looks, Biden broke the law out of disregard for the relevance of these documents. Trump seems to disregard the authority of the law over him. Not quite the same thing.
