Conservatives don't actually believe in "small governments": that's just another posture they take, like "states rights" or "protect the kids". Deficit increases much faster under Republicans, and Trump is no exception. They're funnelling money to government contractors through a bloated military whose sole purpose is spending tax payer dollars on expensive and useless toys, that can't even win a war against a theocracy that's been under sanctions for half a century.
That's how billionaires became so much richer under Trump, while the rest of the country goes to shit. And that's a common symptom of fascism: a merging of the State's and corporate interests.
