Border control prior to it was more focused on customs taxes, and in some countries, keeping undesirable races/religions out.
We have decided the latter is wrong, so instead of directly banning, say, Chinese or Jewish immigration, we replaced it with quotas on country of birth/origin.
Before WW2 the state only helped those who couldn’t help themselves. Now the state just fucks everyone.
Not...really? Unless by "state" you are broadly including the church and other philanthropy.
Through much of human history, the state largely 'helped' the aristocracy maintain a monopoly on wealth and power, through frequent applications of violence against their political enemies. In fact, in ~all non-democratic, and in many democratic societies, the state and the aristocracy - and thus, their interests, are often indistinguishable.
But either way, what does any of that have to do with passport controls?
I wonder if the same will happen to online travel pre-entry-authorizations.
During Covid many countries implemented pre-entry-authorizations, similar to US ESTA or Canadian ETA.
Even if the Covid emergency state has been over, some countries that didn't have this forms before, still require them for travel.
