I do not have the experience to answer this, as I am young myself. I think that as people settle down, buy a house, and have the money to do things they want to do, they are much more likely to be less radical and are more likely to support limited government than those who are young and want to squeeze as much out of the government as possible - especially when more left leaning governments promise things such as free education for university students.
I myself am a supporter of the New Zealand National Party - which is the main conservative party in my country. Most people my age support the New Zealand Labour Party, which is a very liberal - in many ways socialist leaning party. The Labour Party was elected in 2017 after 9 years of a conservative National Party government and they promised students a year of free university education. I’m not drawn in by that, but I can see why some people might be.
