The country had a full report on the failures that lead to it (https://www.9-11commission.gov/) and has done extensive work to prevent it. We are able to know about the mistakes they made because it was made public.
No matter how bad a president is perceived to be, I’m not sure we will see him or her jailed for their actions. It would be too partisan and divide the country. Every future candidate for president would be concerned that they will be charged and jailed once out of office, and it would weaken the candidate pool until someone got in who would be able to mount a resistance of the impending arrest after coming out of office. The checks and balances of the branches of government, and the American people, are responsible for limiting the President’s power in office.
Those who were responsible for the lives lost on 9/11 were held accountable. Our government brought them to justice.
Democracy is not perfect, but I’d argue it’s the best system humans have invented for governing, and I’d not rather live under any other system of government.
Your comment on healthcare is a different topic altogether, but we have some of the best care in the world. We have the top medical schools and training and research. Is it perfectly distributed? No. Frankly there isn’t enough to go around, and when you have competition, by definition 100% of the population can’t receive care from the top 5% of doctors. Billing and insurance are a mess, but I don’t think you’ll find anyone argue that. It’s awful that medical bills are a major driver of bankruptcy, but if you walk into any hospital in the country you will be provided care first, and billed later whether or not you can afford it.
But we know our problems. I don’t think any American says we’re perfect. The first step in addressing them is to identify them. In a democracy it is up to the people in the country to fix it, because the people are the government - it’s not some abstract body who comes in to save the day or a dictator who magically knows the optimal solution.
Authority in America is granted by the American people through our voting and who we elect to office. So that Chomsky quote is interesting, because we’re already organized, and we vote people into office who share our beliefs and serve us as constituents. So we don’t need to undermine authority, because we are the authority, and we can change over time as we vote people out of office.
America has provided more vaccines to the rest of the world than Russia, China, and all of Europe combined. We have countless non-profits that serve people at home and abroad. We very much care about others, and the support for the war in Afghanistan (and from those who wanted to maintain the force of 2500 troops to keep order there) was driven by the fact that we care about the women and children there who are now being oppressed under Taliban rule.
