Why American politics are polarized:
The linked article I'm referring to provides an insight into a problem that and many others, possibly you the reader, and I similarly perceive. But I've not been able, and the author hasn't suggested any feasible remedy.
Relative to this topic, I'm acquainted with at least one person in particular, who faults the Democratic Party for Medicare and the Affordable Care Act for his family's increased insurance and other medical costs. I contend that medical costs in particular are increasing more rapidly than other costs driven by inflation, due to many other than our government's policies regarding medical goods and services. Rapid advancements in technology have given us longer lifetimes, but not necessarily better lifetimes. The much fewer options available to us in the past were much less expensive than these medical advances we now expect to be provided for us.
(I remember when I purchased a car without air-conditioning because an air-conditioner for that economy model would have been an additional cost of approximately a quarter of the price I paid for the entire car).
I don't doubt substantial portions of automobile repair increases, (auto-body repair costs in particular), are due to insurance purchasers and third-party, (i.e insurance companies' practices). I also believe due to the law preventing government administration of prescription drug insurance and government's legal inability to negotiate prices charged for prescription drugs in USA marketplaces, my prescriptions cost more than otherwise.

Social scientists say polarization is increasingly based on a visceral dislike for the opposition rather than extremely divergent policy preferences. By Joel Achenbach. …
… The tendency to form tightly knit groups has roots in evolution, according to experts in political psychology. Humans evolved in a challenging world of limited resources in which
survival required cooperation —and identifying the rivals, the competitors for those resources.
“The evolution of cooperation required out-group hatred, which is really sad,” said Nicholas Christakis, a Yale sociologist and author of “Blueprint: The Evolutionary Origins of a Good Society.”
