There is plenty of blame to go around but it concentrates at the top.
I have been preparing for this since early January, have you? If not, why not? If not, you fell into the trap almost everyone else did to fail to recognize the threat and the exponential nature of the threat. So stop throwing stones from within your glass house, and look forward. Critique the actions of leaders who are behind the curve today, not those who were behind it yesterday. The finger pointing backwards can happen later: for now, we should focus on course correction and survival.
Also, I did some more research, and it sounds like the tweet I was referencing above was in fact misinformation. So I stand corrected on that one! However, it was certainly the case that at the time flights were being called to be cancelled from China, there were accusations of xenophobia being through around.
These are not mutually exclusive in any way.
Getting rid of Trump and replacing him with someone who would have handled this much better is great. Replacing Trump with someone who would have handled things about as well, keeping all the other political leaders who dropped the ball on this, and not changing the deep structural issues that have made things worse, will do little to help.
I just did a search for news articles from the end of January to the end of February, and only found articles like this one[1], where politicians are criticizing the Trump administration's communication, but aren't callng for stronger efforts or mass mobilization (and the article has a quote from Pelosi saying she has confidence in how the CDC is handling things). Congress wasn't passing legislation to fight the pandemic as things were heating up, and governors don't seem to have made effective plans. The media didn't consider it to be a major disaster until recently (it didn't get brought up in the presidential debates until a couple weeks ago, IIRC). Issues like our lack of emergency stores for things like masks and our lack of an ability to manufacture them here is an issue that goes back for years, as is the poor safety net that leaves Americans so vulnerable in times like this.
Hopefully this crisis will encourage people to look at the poor leadership America has had across the board. Simply getting rid of Trump and calling it a day is just rearranging deck chairs on the Titanic.
