The things that each side fears losing (on a given political issue)

Conservatives believe that society has made massive leaps forward in the past 120 years and want to preserve both the improvements and the structures that enabled those improvements. Technological innovation, investment, globalisation, and corporate capitalism have improved the lives of billions of people, and offer the best prospects for the future, but are routinely described by the left as the rich taking advantage of the poor. For example:
Snipped quote from Elections thread: “most [of] us don’t wake up in the AM wanting to smack Jeff Bezos or Mark Zuckerberg in the face.”

Two people who more or less created new modern industries deserve violence and property seizure because they were successful. If you’re going to caricaturise the right, I’m going to caricaturise the left. Believe me, right now in Britain there’s more than enough left-wing idiocy to ridicule.

To address the OP, what conservatives fear are misguided emotional campaigns that won’t achieve anything other than a lot of needless spending and may actually be counterproductive. Quick example: California High Speed Railway.
