Authoritarian rule can work until it doesn't. It can even work better than democracy for some time because decisions can be made quickly. The problem that when it doesn't, there's no path for self-correction.
The US is dragged down by an archaic political system designed for a pre-industrial society of slavers that immediately devolved into a two-party binary of entrenched elites - a system the US doesn't even spread when it does nation building because it's so fundamentally broken.
So yeah, the solution here is just don't be like the US.
