So, two things I really value are free trade and open immigration. On reflection, weirdly, it's somewhat easier to make the open borders case to people, even though it's less popular overall. Why? Because to make a case for free trade, you have to argue the period from the mid 70s to Trump, where trade was getting more and more free, was broadly a good time. But that's not people's intuition, and in my experience, people don't usually accept macro stats.

(possibly this is specific to my bubble)
