It's not easy to divorce "culture war" from "problem solving", since the question of whether problems even _exist_ and need to be solved is frequently a culture-war issue.

For example, you can't pursue "energy modernization and decarbonization" in the USA without taking a side in the "does anthropogenic climate change exist?" culture war.

Any infrastructure plan, whether heavy-infrastructure or social-infrastructure, touches the culture-war questions of "should the government subsidize industry?" and "should the government subsidize the working class?"
