That's a good take overall. One additional point, as an European who has been to the US quite a few times: Hyper-Individualism. I always felt that with the unlimited upside in the US, there also comes unlimited downsides - which society overall doesn't "see" because it's so hyper-individualistic. Everything, good or bad, is purely attributed to the individual, even though it's really collective, structural problems. Example: When you look at certain districts in cities like SF, LA or some places in Texas that I've been to, as an European you'd talk about a failed state and/or 3rd world country where it is even hard to comprehend that such places exist in a country like the US. Whereas the Americans I've talked with put the situation largely on the individuals involved.

Let me tell you about the real difference between America and Europe. Obviously this post I'm quoting is parody, and funny. But I'll share some actual true stories fwiw. I'm an American living in Amsterdam and own a US-based consulting business. There are incredible benefits living in the NL/EU that my fellow Americans back home just don't have, structurally. The two societies are very different from an economic and commercial perspective. Pros and cons. Trade-offs. My motivation in writing about these differences is, in part, driven by some hope that we'll wake up and solve the childcare and healthcare cost issues that plague self-employed Americans (~10% of working pop). 80-90% lower healthcare costs (game changing if you're self-employed and have kids). What we think of as "charter schools" back home are free. No cars... bike everywhere.. walk everywhere. Rent is high for EU but incredibly low vs the US. The list goes on. However, you pay for this. Taxes are high. I even have a temporary tax incentive as a "highly skilled immigrant" yet I still pay an income tax rate 10 points higher than my US rate (which I still have to file/pay, of course, and I do so gladly). When the incentive expires, my rate will spike to ~45% blended. Salaries are also very low. When I moved here I actually worked shortly for a large global firm as a Director of Sales. It took weeks to have my base salary approved because of a law that stated I wasn't allowed to earn a higher salary than someone with the same position whom had worked at the company longer than I had. And the base salary was only a tad above 100K (heavy commission structure). Then there's the standard "COL" reduction from New York for the same exact job was 33.3%. So if your all-in comp is $300K in NYC and your company transfers you to the Amsterdam office, your comp can't exceed $200K... again if it can even get approved depending on whether that's "fair" to longer-tenured employees in that office. These laws/policies/norms are what keep employee salaries low -- entirely by design but underpinned by the culture of the people living here. It's culture. Google "maaiveldcultuur" or "Jante's Law"... there are many variations of this culture throughout Europe and the "Old World" generally... the idea that being "above average" in life is a net negative. Obviously, there are exceptions and deep nuance. But these are real cultural themes that dominate broadly and generally the continent. This is why the USA is so incredibly unique culturally which bleeds into economic and geopolitical power -- whether it's pretty or not... whether you like it or not. America is like Europe's "corporate spin-off" from the 16th-18th centuries that's since grown into something unimaginable. The outlier risk-takers, fantasy-seekers from the European population who would never have otherwise had the opportunity to build anything at all -- no fresh geopolitical canvas on which to create an entirely new culture. So back to the money... in the NL and throughout the EU, even in high-cost desirable Amsterdam, making 100-200K as an employee is quite rare. Those making this are typically expats or higher level execs working for US or global firms in EU satellite offices. But again, nobody really cares at the same time. There is no "how much do you make?" culture. You, frankly, don't really need that much money to live comfortably. All of that said, as an ambitious American business owner I am sometimes annoyed by the culture. I was (and am) so pumped to "get back to work" after the holidays.. growing my business.. knocking down doors. So Monday morning, I hung my coat on the rack in the inner lobby of the office rental complex. Was planning on a latish night given all the stuff on my list. I didn't know tenant keycard access for that area shut off at 6pm. So when I left at 10pm and couldn't get my coat I was livid. But some lower floors had access and I tried to find anyone to help. I was literally the ONLY person in the building at all.. and there are probably 50-100 companies that use the office building. Complained about it this morning, in a somewhat friendly playful way.. and the desk staff was shocked that I was working at 10pm.. could not fathom it. They were even annoyed at my suggestion they move the coat rack to the actual common area. It's the first day of the year!! 10pm is early!! And that, my friends, is the difference.
