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)
I think you can make a strong case that politics is very frightening right now, and could get much worse very quickly, but it's hard to argue the world got economically worse during that period.
Part of why the case is also hard, btw, when you're talking to more right-wing people, is a very strong moral argument is to says "a billion Chinese people came out of poverty." Obviously doesn't work for everyone.
Free trade let China sell products to other countries, and let other countries move manufacturing to China. All that money flowing into China helped pay for the investment and development.
