Yeah, the magical American is the reason for US tech dominance. There's a reason why the biggest software companies come from big countries:

1. large internal markets provide more funding and more competition at the start

2. which leads to better product-market fit

3. which leads to more dominance as the natural software monopolies happen

4. which leads to easier taking over of smaller foreign markets

Biggest software companies? American and Chinese. Also Indian ones are starting to rise, too.

In comparison Europe is super fractured. Ignoring big US companies, the average French person buys stuff from a totally different website than the average German, for almost category you can imagine.
