Requiring immunization is a cost-saving measure for countries accepting travelers. The last thing a poor country needs is richer people coming in, getting sick, and ending up hospitalized all while infecting other people.
And the system has hundreds of years, if not millennia, of history. Before immunization was available, quarantines were mandatory even for people without visible illnesses around the world. It's only in 2020 that the idea of this become controversial and some people acted like it was unprecedented through exposure to echo chambers.
Any source you could reference about the general practice of mandatory quarantines prior to immunization?
It was unprecedented in our life time. That's all people expressed. Not acted like. At most that's what they believed.
Please educate us on how the world worked. Provide some sources, and not only a reference of occurrences of quarantines used throughout history, of course the practice existed, but I read your claim is that it was general practice.
Quarantine is a measure that always existed under serious circumstances, where people would most likely spread a disease causing certain death to healthy, whether young or old people. Today these quarantines are absurd measures causing far more harm that supposedly contain the spread of a virus. Which is spreading anyhow.
Following your logic, going to some extreme would lead to any pathogen discovery on anyone could grant a total shutdown of the worldwide traffic, stop all commercial activity, have every single person assigned to residence. The logic is dangerous beyond belief. You mention echo chambers, it applies to all sort of ideas, not only those you disagree with are echo chambered. there is something even more worrying, it is how institutions influenced by profit makers use propaganda to shape the way we think, and to see that you and many others don't have the respect of other people's appreciation. Do as you please, take all the necessary measure you feel would keep your safe. But Respect other people's freedom.
The question is who pays. You want quarantine, that's fine. Pay for it. Pay for the cost of quarantine facilities and staffing where they exist. And pay for the burden imposed on those mandated to be quaranrined. Those who agree with quarantine should accept the cost, not imposing it on everyone. Why? Because you would then quickly realised the true cost of it and start realising the absurd compromise made with those measures. Right now the impact is diluted across government spending, delayed economical, sanitary and mental impacts. So we go along with disproportionate measures until we can measure their true costs
Take a serious look at whats going on across European countries with these mandates. It doesn't make mainstream news, but pick a few countries and find see the growing number of street protests, and the growth in participants. France currently has spinning up movements as a support of medical staff. Hospital employees claiming the measures such as forced vaccines are absurd, lost their jobs as a result of their stance and are actively voicing their concern. Perhaps they are more ignorant than you about history, maybe they are in echo chambers, but please don't make it seem like we have lunatic medical measure deniers on one side and conscious well educated who support ethical measures on the other.
