All the travel restrictions, testing, school closures, quarantines, vaccine mandates, etc. are accomplishing is imposing costs and creating chaos.
People will be hospitalized. People will die. Hospitals will be overwhelmed.
It's unavoidable at this point, but no politician or policy maker has the courage to admit that.
COVID might have been containable with massive travel restrictions, testing, and contact tracing in the first couple months of 2020. Between the testing screwups, the factually challenged political posture adopted by a certain former POTUS in the early days of the pandemic, the WHO's general incompetence, China's questionable actions, the disease's ease of transmission, and the delay in travel restrictions, that scenario is long gone.
We're all going to take our X% roll of the dice against COVID. You can have a better roll if you get vaccinated, but then you have to consider: (1) The Y% chance the vaccine has a side effect that wasn't caught in trials and won't show up for years, and (2) The cost of meekly accepting that the government of a free country has the power to force people to get a medical treatment they don't want by taking away their ability to work or travel if they refuse, and also the privacy implications of allowing airlines and employers to ask for personal medical information, and the establishment of centralized databases for that information to deal with people who fake vaccination cards.
(I personally got vaccinated, but I'm not getting the booster; reason (2) above is a part of that calculus. Another part is that when I got the first vaccine, I justified that decision by reasoning that long-term side effects are unlikely as the MRNA, adjuvants, or other weird leftovers will wash out of the body within months. That justification goes out the window if the vaccine's not a one-and-done and you start accepting boosters.)
It's not a choice between (a) Massively disrupt these kids' lives, or (b) they catch COVID and some of them die. It's a choice between (a') Massively disrupt these kids' lives / educations, and some of them catch COVID and die, or (b') These kids have a reasonable education and some sense of normalcy, even though some of them will catch COVID and die.
It's the truth. Unfortunately, no one who has real authority to set policy is willing to admit it out loud.
