When I was in college (graduated 2016 so not THAT long ago), I took a class in which I was the only free-market advocate. All of my classmates identified as socialists, or in a few cases, authoritarians. I spent the first few weeks arguing with them, but eventually gave up. I couldn't give them a reading list, I couldn't give them Hayek or Mises, and I didn't know that I could get free copies of I, Pencil from FEE. I wish I could go back in time to that class with the newest tool for advocacy- the truth that you can't whine about capitalism in a Patagonia sweatshirt.
You can't call capitalism evil if you have an Amazon account. You can't complain about capitalism if you've downloaded Uber. You can't decry an evil system if you go to a grocery store and everything you need is there. You can't complain about capitalism if you chose your outfit. You can't moan about capitalism at a private school.
I wish I had pointed out all the fruits of capitalism on my classmate's bodies. I wish I had pointed out the cornucopia of choice we lived in, and how that wouldn't be an option in an "equal world" in which the state provided our needs.
If you're still in college (maybe you're a Campus Ambassador,) try this one out next time you meet a socialist in a Patagonia sweater.
