It's extremely common for people whose personal circumstances change for the better to switch from the left-leaning politics that got them there to the right-leaning politics that seems like it will allow them to keep it.

Second generation Indians and Pakistanis in the UK, for example, have historically voted Conservatives if they've made it to the middle class, whereas their parents and their lower- and working-class peers tend to vote Labour or independent middle/left parties.

Of course, these same people would say that the saying “If you are more fortunate than others, it's better to build a longer table than a taller fence” is a good one, but then proceed to vote against that exact thing.

Atomised and egotistical thinking, when it comes to voting, is ultimately self-defeating.
