In (partial) defense of Hamilton, there is good reason to believe his preference for a stronger executive grew out of a sincere belief that something close to an elective monarchy was necessary if a Republic was not to descend into chaos and fall apart.
Events in France a few years later showed that his concerns were not entirely unfounded.
He turned out to be wrong, but that is no reason to assume his proposals were based solely or even mostly on a lust for personal power.
Events in France......
The French Revolution was a temporary descent into chaos and mass murder.. But it was preceded by the centralized administrative state set up by Louis XIV to weaken local autonomy, and was followed by an even more centralized national state under Napoleon and his successors.
That said, in my opinion Hamilton’s desire for a strong federal government probably was more about correcting the excessive looseness of the Articles of Confederation than about what he saw unfolding in France (BTW in any future Anlgo-French conflict, Hamilton favored strict neutrality).
