It's a difference between EU and US philosophies on regulation, particularly regulation of _competition_ issues. Broadly, the US's attitude is "please, companies, consider doing this, look at this big sack of subsidies", whereas the EU's attitude is "do this".
(This wasn't always the case, and in fact at one time the US was tougher on competition law than Europe was, but since the late 90s the US has been largely asleep at the wheel on competition.)
And the US only established a national charging standard that it can incentive in February 2023 at that. https://www.federalregister.gov/documents/2023/02/28/2023-03...
Great stuff too, imo. Not just about charging plugs, but specifying standards for how cars communicate with chargers, mandating open APIs to show real time availability info (how many stations providing what charge outputs are available right now?); a full suite of requirements to make sure people can find working chargers & that cars can work with them.
