In general, I think most nations should have more closed door policies like China. My country (which won't be named) does not have a startup ecosystem anymore and we have become a consumption ground for one silicon valley startup after another. Instead of fostering local startups and paying some money (since many bootstrap and do not have big pockets), all the companies just take the freebies of silicon valley startups. We had a local chat start up but slack ate their lunch. Everyone here just uses the slack free tier. How do you compete against free?
Eventually, this has led to all the data of individuals and companies on US soil (or wherever those startups feel like stashing the data). We have no control or say over it. If we are to look for alternatives, there is none in our own country.
And for those who think the world is one giant land where everyone can roam freely, it's impossible for me to move to any of the western world because of visa restrictions. And US has the harshest work visas on the plante.
