I think there's something to this. And while America has always had this can-do attitude (just look at the number of self help books), it does seem to be in another gear recently. I don't know what caused it, but I think there have been a number of indicators: Trump ignoring Congress and introducing wild tariffs, Musk firing half of Twitter's staff and then later repeating this with DOGE, the quick roll-out of LLMs. There seems to be this prevailing attitude of "we can just do stuff, damn the consequences".

It appears to come with a lot of corruption and anti-intellectualism. Like you say there are also benefits to this. I think the break through of mRNA vaccines was an early indicator. I just hope we can steer this attitude back to a more optimistic world-view instead of the blatant self serving one that is currently prevailing.
