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.

That saying holds more truth if you're using the "non-political" definitions of conservative -- i.e. moderate, cautious, or resistant to change.

Moreso "set in your ways" as the world changes around you.

People who aren't liberal when they're young have no heart.

People who aren't conservative when they're old have no money.
