Congress has become increasingly unproductive and unresponsive. There are many popular policies that Congress essentially ignores, and many problems that go unsolved. So trust in government dwindles and people crave strongman solutions.
I’m not sure there is a solution. There are so many interlocking problems gumming up the process that any “we just need to fix X” solutions (where X is gerrymandering, money in elections, lobbying, the two party system, first past the post, corruption, income inequality, the electoral college, the slow death of journalism, consolidation of industries, etc) are nearly impossible and also probably insufficient because they all feed back into one another: they are both causes and effects.
So when people are mad about a downstream effect like the price of eggs and digging any deeper touches one of the topics above (“to fix egg price gouging you need to reinvent the political system” sounds a lot like “to make an omelette first you need to create the universe”), it’s really easy to throw your hands up.
