Since the 1990s, the Dutch Olympic Committee has treated sport like a business. Funding is directed toward disciplines with real medal potential (sailing, rowing, (track) cycling, hockey) rather than being spread thin across every sport. These sports that receive the most funding also happen to not be among the most popular Olympic sports if you look on a global scale, so less competition.
Sports that we’re not particularly good at but where the competition is high, such as badminton and table tennis get no funding, whereas breakdance, darts and freerunning did get some funding this year.
At the same time, I think sports seemed to have become less important in the eyes of the governments of other (mainly Eastern European) countries such the former Soviet countries, Cuba, Romania and Bulgaria. As larger nations such as Russia and Germany restructured their sports systems after the Cold War, the Netherlands really invested in world-class facilities like Papendal and built expertise in these more niche Olympic sports. At Papendal for example, the Netherlands has built strong links between universities, scientists, and sports federations, turning athletes into data-driven projects focused on small gains.
So yes, funding has increased, but mainly for the more niche sports that we have medal chances in. I think the investments in facilities like Papendal and having a lot of the top athletes and talents be centralized at those facilities where they can live, train and go to school, play a much bigger role.
