A couple of caveats about the IRA. Firstly, an Act does nothing in itself. Everything depends on execution, and whether or not forecasts of the Acts effects were good. I know I'm stating the obvious there, but it gets papered over frequently when Congressional victories are declared. Secondly, the US is only one nation. The most influential in terms of global ethos-and-markets-setting, yes, but there's a whole world out here.

I don't personally believe much will improve globally without stronger global governance. I also think the latter is possible, but unlikely within the next couple of centuries. And we probably will be well and truly fucked by then.
