Those are precisely the type of presidents we need... like G Washington. He could have pulled a Julius Caesar, but it was precisely that he didn't want power that he was judicious in its application.
We end up, in this day and age, only with people seeking power getting into power... that's the system. It has to be that way.
Washington has always been highly overrated.
By the time he declined to run for reelection, he was starting to get a bit senile. He had trouble remembering whether or not he had given his approval for many things. Investigations into Hamilton's misdealings came close to uncovering the president's incompetence, and were scaled back for fear that undermining Washington's reputation would undermine the legitimacy of the entire government.
After literally falling off his high horse during the Whiskey Rebellion (when he rode out in force to crush a revolt over taxes which were considerably higher and more unjust than those which triggered the US Revolution), his back never really recovered. The pain was enough to make it hard for him to stand for extended periods to give speeches and perform his other ceremonial duties. His great qualification for office had been his impressive height and physical appearance, but continuing to present such an imposing figure was getting difficult.
Washington probably recognized that he would tarnish his legacy pretty soon if he did not retire early.
He definitely desired power, but he cared more about his reputation and finances than the hard work of actually managing the country and maintaining political dominance. A lot of what he did was in order to advance his personal interests as the nation's largest landlord (since he was the first to survey the land from a distance, despite never working or improving it, he hated the idea that squatters might making a living for themselves there without paying him lots of rent) and a a major investor in commercial ventures (like that large distillery that would profit greatly from regulations which disproportionally burden its smaller competitors).
Washington was a Federalist, Elitist, Mercantilist, Crony-Capitalist, Big Government type. He is not the sort of man whom we needed then or now.
