> What other examples are there? Off the top of my head, so all my counterexamples will be British, but here are a few US tech companies who built missing features for major players - whereas in other countries the major incumbents just built it themselves: * Venmo - real-time money transfer (the UK equivalent is the bank-run Faster Payments Scheme) * Intuit - Self-service tax filing (most UK tax is done for you. If you do have to file, you fill out a straightforward online form ["I earned £___ this year"] and enter your card details. Job done.) * Instacart - Online grocery shopping (a standard service from incumbent supermarkets, eg Tesco/Sainsbury/Waitrose/...) * Apple Pay - Electronic payments more secure than magnetic stripe (most of the world had chip cards ~10yrs ago; the French had them in the 1980s.) I'd say that's a pattern. It's not that the US economy isn't dynamic, it's just...weird.
