All I can say is that the "in the trenches" Epi, virology, immunology people on Twitter have been asking for all sorts of things this whole time, and pointing out things other countries have done in terms of testing, tracing, etc. But they don't decide where the money goes and what the priorities are. Pharmaceutical CEOs and non-medical political leaders do. And they have been acting like everyone else... this has to be all over soon, right? If we do nothing at all, now that we have vaccines, this will be all over. No point in investing in a bunch of stuff that won't be needed because this was just going to turn into a cold. People got vaccinated in May, ripped off their masks and declared they were done with COVID. Why should the money / decision guys have thought people were interested in anything else? And we don't invest in things we can't justify / sell.
If you want effective leadership, first you have to elect people who believe that government action has a positive purpose and can help. Believe that research should be funded. Not people who believe government is the problem or business managers who don't invest in things with unknown ROI. Up until 2020 very, very, very few people even believed something like this situation could happen. In 2021, very few people believed that this situation would continue to have the "bite" it has had. And once Omicron blows through people will be back to being done, and that doing anything COVID related is a waste of energy, resources, time and money.
These things require community action. But since vaccinations, people have been screaming about individual choice as the solution. I certainly haven't seen many people in this thread asking for more community action as much as I've seen people declare it unnecessary. You get what you pay for, you get what you value, you get what you support. You don't get the things that a few knowledgeable people know are necessary but can't convince anyone else about the basic need because others can't even possibly imagine any of this.
