I agree in general terms that the people get the government they deserve. But we know that cause & effect relationships are seldom black and white.
Ike was not joking around in 1961 with his Farewell Address. And while the US citizenry is certainly lazy and oblivious, it is also true that they have been grossly propagandized and misinformed over several generations now, by behind-the-scenes men and organizations that benefit from the status quo.
So there is plenty of blame to go around for the mess we're in.

I agree with everything you say there, especially your last sentence.
I would remind you that the country which we love so much, and the government of that country, are 2 distinct and separate entities, and that as George Washington noted, government is like fire--a useful servant, but a fearsome master.
I always avoid conflating the two entities in conversation.
