It wasn’t always.The American model is that all levels of government are elected by the populace.
Originally, power at the national level was split among the three branches, each reflecting a different constituency. Representatives were directly elected by the people (they still are), Senators were chosen by their respective state legislatures (they aren’t anymore, but in my opinion they should be again), and the President was elected by Electors who were appointed by each state (for the time being they still are).
“All levels of government elected by the populace” would only serve to reflect the will of a majority. It would not allow for representation for both the population at large and the states.
