I've been thinking of good way to teach people what each one means and may have come up with the parable. Wood shop. Yes that icky physical labor lefties hate so much. But it fits.
You step into wood shop on day one and have a choice to make. You can choose to be a liberal craftsman or a conservative one.
If you choose to be a liberal you will have the choice of all pine blocks cut exactly the same, same size, same weight and same grain. And you will make that into smaller blocks, perfectly square if you can but if you can't do that it's fine. You are guaranteed to get a D in the class. You can't make anything other than square blocks, you can never get a C for making better blocks than anyone else but you can't fail either if you never even get a block cut out. It's all fair. No winners, no special treatment for those that did well, everything is equal.
If you choose to be a conservative craftsman you walk into a room full of all kinds of lumber. Oak, Walnut, Redwood etc. 100's of varieties. You can make anything you want, out of anything you want. What you don't get is the guaranteed D for the class. You can get an F, but you can also get an A,B or C. All you have to do is make something people like. If you make perfectly square blocks like the libs you'll probably get an F. Nobody needs those they're pretty basic. Put in a little effort though and the sky is the limit.
If you want the guaranteed barely passing grade you need to be a liberal. If you want the A and all that comes with that success you need to be a conservative. It's really that simple.
