We have an administration that wants to ignore basic data like unemployment. Or obvious ramifications of economic policies (lower interest rates -> inflation). They want to hobble any support for the lower/middle class's mobility, while lowering taxes on billionaires (who themselves are out of touch). They don't see basic facts like draconian immigration policies hurt costs.
Ignorance around economic policy is almost a tenet of faith. Ignorance is taken as a source of pride.
Maybe they were ignorant and dumb to do so, but people voted for the first Trump administration. A crazy guy constrained by mostly sane, non-cultists that administered the government around him. I don't think people who voted for Trump wanted Trump II - a doddering old showman surrounded by sycophantic cultists that delight in doing the opposite of sane policy.
