Theoretically there's no reason why wealthy businessmen couldn't make good politicians.

In practice though, their track record tends to be kind of terrible.

The main issues tend to be
1. trying to run a government like a business, which is just wrong and bad and leads to incredibly stupid things
2. poor co-operation skills: these people are used to being The Boss and tend to be really bad at negotiating or understanding conflicting interests and points of view
3. they're usually super easily corrupted, because they're oriented towards personal wealth rather than public service oriented
4. cronyism and elitism; they tend to be wealthy people who like to surround themselves with people like themselves (or yes-men)
5. Dunning-Krugerism; these are people who tend to believe that they'll make good politicians because they're good businessmen, and that they already have all the necessary skills and understanding because *go back to they're good businessmen*.
6. Often lifelong detachment from how most people love. These people were usually born rich.

I'm sure there's plenty of exceptions, but for the most part I would argue that businessmen tend to be just really bad politicians.
