Yeah you are correct they don't bitch about masks because before Covid they would wear masks commonly because of the pollution on their cities. They have always worn masks, and while I do agree you should wear masks it isn't going to solve everything. Plenty of countries that seem to have "a lot less cases of covid" just aren't doing nearly as much testing as the US is doing.
It was deemed unconstitutional to try and enforce people to wear masks, so that can't happen.
It was stated by the World Health Organization advised that lockdowns are not needed and should only be used as a last resort. In reality majority of people are not dying from the actual virus "Covid-19" but from other thing such as diabetes, heart issues, etc. Which is predominant in elderly people. It hardly affects younger people, unless they have symptoms like those which then they should take caution. I personally am immune suppressed due to having a autoimmune disease in my eye (Pars planitis Uveitis) and the medication I take shuts down my immune system. I personally am not worried about the virus nearly as much as people that have absolutely nothing to worry about. In reality locking down the country is not the way to go about this, open up the economy, stores, business', etc. and the people who can be harmed by the virus should isolate themselves.
As Biden stated: he wants to enforce plexi glass in restaurants, stores, etc. Which is really expensive to do. Business' would spend fortunes on it, and if the Government was funding it then it would be a enormous amount of money gone for no reason. Plexi glass isn't needed.
Yes, people should wear masks, but you cannot enforce them to do so.
But in reality, this virus came out of nowhere and on a massive scale that no one was ready for. The virus was leaked by Chinese journalists and Scientists and now they have all turned up dead or missing. You cannot pin the entirety of the virus spread on Trump like so many people are. He closed the borders to China and the UK pretty quickly. We didn't have nearly enough ventilators, masks, etc. to take care of all the people that were arriving at hospitals. We were underprepared and no one expected this to happen so we couldn't have been ready. The virus was so new that no one knew anything about it, we all assumed it was extremely deadly when it first was announced, now its not. It took time to study the virus, to learn how its spread, to learn the lethality of it, to learn how contagious it is, learn cures for it, learn the symptoms of it, etc. That all takes time to do and the virus was spreading swiftly while we knew nothing about it. We have the highest numbers of tests than any other country for Covid, im sure plently of other countries are a lot worse then they seem but they aren't testing as much. The more we test the more we are finding people positive for Covid. In China they were executing people with the virus at first, and locking them up. You cannot blame the entire thing on Trump.
I would also like to point out, have you noticed anything about the corona virus when the BLM protests were happening? Nothing was being said whilst those were occuring, but they were whenever there were Trump rallies that occured.
The stimulus checks I don't believe were ever done before which helped many people, and there were pandemics like the swine flu, the spanish flu, etc. which btw were a lot more deadlier than this virus.
Trump offered $1.8 trillion for the econimic relief act which Nancy declined. They wanted $2.2 trillion and they didn't get that so Nancy Pelosi got upset and denied it. Not to mention a lot of the stuff in this Economic relief act are scuffed, have nothing to do with the virus, etc. that was created by Pelosi and dems of the house. I recommend reading it if you haven't already.
A vaccine would be wonderful, whether it is later down the road or now. I would rather have them test it and be sure than giving it out to the public without knowing all the side effects. Do you get the flu shot? I know I do, especially being immune suppressed. Stuff like vaccines take time, you don't want to rush companies to just spew something out there not knowing everything about it. If it was a successful vaccine, then maybe we wouldn't need to wear masks, stay 6ft apart, etc. Who knows, but in reality I do believe that Trump is trying to help with the virus, but it isn't all in his power and he doesn't control everything.
TLDR:
It wasn't only Trump's fault that the virus is as bad as it is right now and he can't do everything you expect him to do.
