Liberals, in the political science sense, do not believe in taxing the rich or corporations being untrustworthy. Liberalism is a market-oriented philosophy that seeks a smaller government where possible.

I get that. And it can be used to summarize some kind of financially comfortable type that (wrongly) thinks the economic system works and that businesses/corporations can be trusted, but also likes socially liberal stuff and hates Trump trash.
