Plenty of tech companies in Europe either way; you just don't know about them. Do you think Europe is some poor underdeveloped continent with uneducated people who can only "write spreadsheets?" What a patronizing comment.
Europe has some companies with IT departments, some American companies with European offices, and some no-name consultancies (which are often US-owned). The indigenous European tech industry is a complete joke, since there is hardly any of it.
A normal programmer in Europe earns maybe $2-4k per month, or $24-48k per year. For context, the American poverty line for a family of four is $24.3k, so they are earning about $21/month above the poverty line.
A normal programmer in the USA earns maybe $100k per year, and up to $300-400k if they work at a big company. In Europe, the CEO of an ostensibly big company might earn $300-400k. It's an utter joke.
That I haven't heard of the alleged European tech companies just goes to show my point. DeepL, what the hell is that? Spotify is somewhat larger-scale web development, but still just a Mickey Mouse startup. The NYSE couldn't even get their flag right! The other two (relatively serious companies) are located in the UK, which is slated to leave the European Union soon.
