I've owned three American basses. A 75 reissue American Vintage, a Deluxe Jazz (both now sold) and a Precision Elite.
I bought the first two second hand and the Elite new. The RRP of the 75 reissue was about £2.5 k, when bought new, and the Elite cost me £1.9k.
The two Jazzes played beautifully with very low action.
Were they worth the money, if bought new? Well you can buy a less expensive bass and take it to a guitar tech who will get it to play fantastically.
I have a parts Jazz, with a Korean Squier neck, and a vintage modified body, which has been set up really nicely and plays as good as my American Jazzes did.
I own a Japanese Fender that also plays beautifully.
So logically, buying American doesn't buy you a bass that plays better than a much cheaper instrument, so you may ask 'what's the point in spending so much more money?' .
Is it kudos? Peer pressure? The American dream?
I bought my American basses because I wanted a 'Real' Fender, not one of those copies from overseas (however good they might be).
Ironically, when I bought my brand new Fender Elite it didn't have 'Made in the USA' on it, because, legally it isn't actually an American bass, as too many components are made overseas. These days Fender instruments have 'Corona California' stamped on them instead.
