Especially when you used to hear certain people who were/are themselves immigrants say to others, “go back home”.
That's why I tried not to be too hard on immigrants in Suriname at the time, because I could get why they left their home country. As long as they add value to the country and aren't a nuisance, then be my guest. Only, don't steal our wealth, like gold for instance. Pay the necessary taxes, but I guess controlling and regulating those sectors is the job of the government.
But these borders and passports while they serve a purpose makes you wonder if there is a better way. A more equal way.
I would like to travel the world, but with our passport there's only so much we can visit.
