The Eastern and Central European countries have always felt much more dynamic and open to work hard.
There's a reason why the countries on the lefthand side of the graph provided are also the ones with some of the better innovation industries in Europe.
There is still much work to be done in the CEE, but I'd be fairly confident that they'll become truly developed first world countries in the next 10-15 years, and some already have such as Czechia.
Andreas is exactly right imo - his points about simplifying incorporation (there's a reason why CH does so well) and normalizing English (there's a reason why every developing Asian country from India to Vietnam to China is pushing English fluency, and lots of the CEE countries) will help.
German, French, and British government officials are the worst to deal with imo - they will bend over the barrel for local conglomerates but ignore domestic challengers. Datadog could have been a fully French company, but the French ecosystem stifled them.
Also, ime - Western Europeans seem to idolize Finance, Law, Management, and Civil Service careers more than innovation or entrepreneurship, unlike their CEE (Germany and Austria excluded) peers.
