Earlier quoted context omitted.
Why are these numbers so massively different across the world? Do European companies generate that much less revenue? Or are labor unions in Europe just that much less effective at bargaining? Or is productivity that much lower in Europe? (I'm not sold on any of these)
If you're a European developer and underpaid, are you going to start your own company to do the same work but sell it yourself and take all the margin? Probably not, from comments I've seen here, it takes an awful lot of work to make a legal business. In the US, it takes minutes to incorporate, and even less time if you don't care to incorporate and just want to file a Doing Business As to use a separate name. Busine…
It depends on the country and the government there, i'd say, as well as how technologically advanced they are. Here in Latvia, it's actually not too hard - you just need to fill out a couple of forms, take care of the starting capital and payments and then you'll be registered as a company. In addition, there are various types of companies, to support small startups as well: https://www.ur.gov.lv/en/register/
That said, i believe that taxes and such are a tad overcomplicated in most countries, though there probably are a few good arguments against making most of the bureaucracy a bunch of online forms with prepopulated data, with which i may or may not agree.
Of course, for many, other aspects of actually running a company are what cause difficulty - everything from doing sales to marketing, as opposed to just writing code and architecting technical solutions.
