Reinforcing my Prejudices

Passport possession by state correlated with education and income levels here.

So, should we make people travel? Would this reverse-engineer wealth creation? Or, to put it another way, does travelling abroad induce people to come home and make their lives better? What’s the driver?

Someone will say that foreign travel turns you into a weenie. I did read that only 1/3 of the members of the House of Representatives has a passport.
