Nationalism and Stupidity?

Unfortunately, I can't help agreeing with journalist, Nick Cohen. The world's rich nations, due to their nationalism and stupidity, have not dealt with the Covid19 pandemic at all well (https://www.theguardian.com/commentisfree/2021/sep/25/why-cant-we-tackle-covid-and-climate-heating-nationalism-and-stupidity). Cohen describes our failure to vaccinate the world as 'astonishing'. The rich nations, leaving millions to die needless deaths, is clearly a moral affront. Cohen also maintains, however, that the rich nations clearly don't recognise their own self-interest. Many authorities have pointed out that failure to vaccinate the world, means that the virus is still out there, mutating. This, however, isn't the only gap in understanding on display by rich nations. The International Monetory Fund estimates that, if Covid continues to spread, the world economy risks losing £3.3tn by 2025. The cost of vaccinating everyone on the planet is a mere £70bn. It's a bargain! We prefer, however, to throw past-their-expiry-dates vaccines away, after initially hoarding them. Nationalism and stupidity also seem guaranteed to make dealing with the climate crisis next to impossible.
