87% of Americans think there is a "major role for government" in ensuring safe food and drugs. 75% of Americans think the same about protecting the environment. 70% think the same for education. 61% think that about healthcare. The FDA, EPA, Dept. of Ed., DHHS aren't going anywhere.
Americans don't dislike our institutions. They dislike the people running our institutions (74% think politicians put their own interests ahead of the country's).
That said, there are, I feel, realistic causes for concern. Although GWB didn't "dismantle institutions" he did get us into an unnecessary war with Iraq. Similarly, I'm getting a little afraid with Trump's appointments about what's going to happen in Iran. (That said, had Hillary won, I'd be feeling the same right now, probably, but towards Russia.)
