I had measles in the 1980s as small child - the vaccination programme where I lived was slow to get off the ground - and it nearly killed me. In 1980 2.6 million people worldwide died of measles, a very large proportion of them children. No one ever considered a lockdown, it was never even suggested.
This is an absolutely spectacular example of false equivalency.
Measles has had a vaccine since the 1960's. And before that, it was an established disease, most kids caught it, meaning that a large portion of the population had already had it and were immune.
So even though measles was objectively a "worse" disease, it wasn't novel and outbreaks tended to be staggered, so there was never going to be a situation where an entire massive population all suddenly got it at once and started dying and overwhelming hospitals.
Covid19 is NOVEL. This is a really, really important point. There aren't generations of people with existing immunity built up.
So it's a highly infectious disease, where a significant proportion of cases will end up in hospital and absolutely nobody is immune to it. That's basically the holy trinity for shit hitting the fan.
Lockdown is not a new concept. There have been other lockdowns in the past for novel pathogens, just not in your lifetime, OP. And sure, lockdown isn't a perfect situation but without it, this disease would rip exponentially through society, middle ages style. The economy would still tank in a different way, through a sudden spike of mass illness and hospitalisation of the workforce. That 1-2% mortality rate would shoot up because there wouldn't be enough healthcare resources to treat everyone who was sick, so people who might have otherwise survived with medical treatment would die. We'd see a knock on mortality effect from hospitals being overwhelmed.
I'm seeing a lot of people who are starting to think it's not worth it and they're saying "but oh look, it's actually not that bad". This is really flawed reasoning. Tens of thousands are dead even despite the lockdown. Without the lockdown, without social distancing, that figure would be unmanageably greater. We are currently living some approximation of the best case scenario. I'm sorry that it still sucks but the alternative is worse.
