Out of all the comments here, I'm glad to see so many bring up the one and only reason any governments ever fail on their own - corruption.
I spent three years with my company selling into the Trump administration. I had a solution to the American energy crisis. After my company closed, because I couldn't get a call back to save my life, I learned that there were no people at the offices I was calling. Trump left 35% of the renewable energies offices unappointed.
I'm bringing this up because no one here is mentioning the elephant in the room. Trump completely eviscerated the CDC epidemic watchdog groups, the CDC funding allocated for emergency response, and the FEMA funding for epidemic response. Our government didn't fail. We lacked infrastructure to chase the answer we needed in a timely fashion.
Looking back at all we've lost, this grave time will actually spur a much larger scope of growth over the next 20-30 years. We will have another roaring twenties. Yet, here in the US, people walk around talking about how little the government works or how incompetent lawmakers are. Well, it's not all of them. Just enough of them that they keep the system gummed up.
Term limits are the singular answer the US needs, now more than ever. It could beat back the corruption we see from the likes of McConnell and Pelosi, two people more concerned with their grip on power than actual for-goodness changes. But as long as Trump remains relevant, we will see a vast division among lawmakers, which will destroy infrastructure built by the government to help people. The voting rights laws being rolled back in Georgia are a fantastic example. However, on the grand stage, those same supporters can never win any real gains. This boils down to the fact that his backers do so based on a lie. As long as that lie exists McConnell and Cruz, and their like, can never engage in any advancements for fear of being killed by Trump's base.
If Trump had followed his supporters to the Capital on Jan. 6th, our government would have failed. We were close. It's a good thing he's more interested in tv ratings than reality.
