The number one thing about the US is the sheer hope and belief in the future. Europe, maybe apart from France, surprisingly, is depressing and nobody thinks the future is bright.
I remember that vibe before 911, I remember every year there was a notable invention/increment in technology, and about after the 2008 housing crises, the vibe ended or was noticeably being phased out, now every year google/smartphones/gaming/climate/cost of living/politics gets worse (dark patterns, SEO spam, DLCs microtransactions, etc.).
Most people in the US who aren't old enough to own a home have watched home ownership evaporate away from them as costs skyrocket and rent-seeking corporations snipe all affordable stock with can only offers.
The US is a depressing place that kind of sucks if you're not coming here for a high-end tech job or as a rich celebrity.
Maybe so. But then you see the sheer hopelessness in countries like the UK, Canada and Australia and you realize the US is still where things can happen.
I think the future is pretty bright here in Spain. More importantly, I think things are really fine as they are. We just have to keep the climate deteriorating in check because being in a hot country we're really starting to feel that here.
But overall yeah things are fine. Not seeing great pies in the sky for our future but no big sinkholes either.
