To "protect the country" isn't very specific. You're also pretty unclear on what you thought he should have done regarding travel from China. Do you think he should have illegally prohibited the 40K American citizens from returning to the US? Do you think he should have allowed Chinese nationals to come to the US?
The rest of your post is inaccurate when it isn't word salad.
Mobilize the resources available to produce tests, protective equipment, and workplace or public area safety measures to slow the spread of the virus.
Instead, he sent checks to every American. Awesome. Borrowed money doesn't keep the virus from spreading.
In a different thread I said the government should have hired people to deliver groceries. In reality would that have been a great idea? This is where project managers earn their pay. What does it take to get that from idea to program? Could it have been done? I don't know, but yes, I honestly believe that would have been a good use of government money. It employs people while simultaneously slowing the spread of the virus.
But, maybe that wasn't the best way. Again, that's what project managers are for, to figure out which, out of all the possible things to do, are actually the ones that can be done, and then do them.
Why do I not have an N95 mask? Would it have been impossible, with the resources available to the United States, to make five of them for every single American, with 20 times more than that for health care workers, over the last two months? That's about 2 billion masks. Could it have been done? I don't know, but somebody ought to, and I don't think Trump did.
In this thread, I think, there was mention of an Apollo level effort. A truly massive and very expensive undertaking to create PPE and tests. Why didn't it happen? He could give away two trillion dollars, but he couldn't make 2 billion masks? What's up with that? That's 1,000 dollars a mask. Surely it would have been a massive undertaking. Good thing there's 30 million Americans available to work on it.
I guess it's not his job......but, wait, whose is it?
