It goes much deeper than that. The notion that work could not possibly be "living" is much more popular in Europe too. With employment so over-regulated and entrepreneurship discouraged it's easy to see why people treat "work" in a very transactional way.
For most people there just isn't a lot of obvious upside waiting for them if they work extra hard. Salaries are extremely compressed compared to the US. The only way to make real money[0] in Europe is by running a business but that's discouraged too.
Even education - there's no Ivy League of Europe, there's no Stanford. There are some schools that may be considered good, but elite - not really.
[0] well I guess anywhere, but there are many diverse career paths in the US that will reliably get you to a few hundred k. In Europe not so much.
