Will the resurgence of American conservatism affect the cultural outputs we receive from America?
On the one hand, it may not make much difference. Most of the American cultural products we get here in Australia come out of New York and California. Both of these remain liberal enclaves.
On the other hand, Hollywood could decide to make more movies that appeal to the conservatives in America. That is possible. Certainly the failure of the feminist Ghostbusters movie must have already given them pause.
It rather depends if Hollywood wants to “leave money on the table” or to make movies to appeal to “deplorables.” Hollywood has made plenty of conservative movies in the past.
