That's really disingenuous. Clearly Biden Jr. was getting paid more than he would have but he probably did have unique insights that would be worth quite a bit of money to Burisma. But the accusation is just that he made a few $100k more than he would have and made some top-level connections (so the money actually seems sensible). Every well read person just takes these things at face value as a single individual fallling up - but he had no true secrets to give and no real power. The corruption within the Trump admin is expansive with hundreds of millions of dollars across multiple businesses and at least in the first administration real power vested in family members.
