People who gain/have a lot of wealth over their life do tend to want to lock that wealth in by being Conservative I think. Wouldn't want to shake things up!
I didn't get more conservative as I grew older. At least I don't think I did. What happened is that the definition of conservative changed.
Criticizing censorship and restrictions on free speech didn't use to be a conservative cause, it is now, so I grew "more conservative" without any of my beliefs changing.
There are multiple things wrong with this, the most glaring of which is that a conservative with money would lack a heart as well. Conservatism is incompatible with having a heart.
