I have heard that said many times.
"You're a liberal when you're young and more conservative as you get older.", variations on that theme.
For me, it has been the exact opposite of that. When I was young I bought into all the "conservative" capitalist talking points. I was a cruel person at that stage of life. My sense of empathy was slow to develop.
As I grow older, I become more liberal. And I mean LIBERAL liberal, not a Neo-liberal anarchist cop-hating punk, not like that. But also I have come to understand over time that the vast majority of us humans want very similar things, with lots of common ground. With social media and all I think the wing nuts have hijacked a lot of the attention, and then these folks are pushed in the media as to being representative of the majority which they are not.
Not going to drone on and on, the main bullet point here is that I personally am developing the exact opposite of what Churchill said. Mileage may vary.
