As noted this is nonsense. On top of some people never getting in the first place, slowing the rate of spreads buys time for a vaccine and sufficient medicine to become available. (Some basic precaution such as people washing their hands also can have an impact.) There is some evidence a specific medication or two do have an impact, and at least if too many people do not become infected too quickly that medication could become available for at least the most serious cases.This topic is quite a lie.
We are dealing with a virus, a global pandemic. It will burn its way through the population and that is it.
The President, our government, our actions... they have nothing to do with the outcome here. Because we cannot change the outcome.
Furthermore fatality rates are going to be impacted by whether at least the most severe cases can be properly treated in a hospital or not. (Its true that part of this has to do with existing hospital capacity which has been impacted by the Trump administration's actions over the last 3 years rather than actions take right now, but that certainly does not get this administration off the hook. It should be noted that a reason we are not in worse shape right now is House Democrats in particular blocked Trump administration's previous efforts to for example significantly further cut the budget of the CDC and the US Department of Health and Human Services.)
