You miss the point. Democrats listen to the wealthiest 10% that happen to be Democrats. Republicans listen to the wealthiest 10% that happen to be Republicans. The parties are two coalitions of the elites. One elite coalition is mostly folks genuinely trying to make the world better. The other....isn't. But it's all a game of elite vs. elite. The rest of us are just along for the ride.

It's not some conspiracy. It's just social circles. Politicians spend their time interacting with the upper levels of society. Even when they are trying to reach out to ordinary workers, they mostly do so through workers in relatively elite positions, like union leaders. Politicians just don't spend much time interacting with normal people, and thus they don't understand normal people's problems. Politicians of either party will hear about whatever things the wealthiest 10% happen to be worrying about at any given moment. And we very much are influenced by those we spend our time around.

What bills the new Democratic Congress passes will have nothing to do with what the public as a whole wants. Whatever the wealthiest 10% who happen to be Democrats want? That is what they will focus on, to the exclusion of everything else.
