First, poor countries will need to double the effort to catch up with other countries or else it will create chaos in that countries and might start a civil war.
I'm only going to address this one point, because the rest of them just descend into wild flights of fantasy, which are perhaps driven by watching too much Walking Dead.
Civil war as a result of poor countries needing to catch up with richer countries because of....what, exactly? You do realize that the US had a surplus of the Pfizer vaccine and shipped a bunch of doses to
Peru and Pakistan, right? And who knows if anyone else is helping out other, poorer, countries as well. And keep in mind that COVID-19 is just a virus that
kills far fewer people per year than things like cancer and heart disease. The fact is that most people who contract COVID-19 recover and move on with their lives--and I've known several friends who've had their whole families contract the virus, and they're fine now.
People are going out of their goddamn minds about this pandemic, when what they ought to be doing is pushing for mask-wearing restrictions to be lifted. This isn't the worst pandemic ever to hit mankind; it's just the most serious one that's happened in
our lifetime. Had the virus been more virulent (or had it been a different virus), things could have been much worse. Don't lose your head over this.
Yes, you had some point but the feeling is different when you are living in a poor country and watching others that are now to started to live a normal life. The thoughts of being negative would eventually come to mind after comparing to others and this is indeniable that others will going to think like what I had wrote to OP.
However, once we got receive help from other rich countries lifting our morale without pushing us to debt then that would be work of great humanity. If so, but if not probably not because all things are done just like business. You need this but I need something in you so we will exchange something for the better and that would be the kind of negotiations it will take and in the end poor countries will then can be colonized or will become slaves due to unpaid debt or unable to pay or the capability to pay.
War is really possible because other countries had started already while orhers are just being heated up by issues and concerns, bully and other means that could start the war. Well, I not need to afraid to die. I myself know and believe in the princple
"Die today, Die tommorrow, the same thing were all gonna die"
