There is this concept in the Nordic countries called the Law of Jante:
"The Law of Jante (Danish: Janteloven) is a code of conduct known in Nordic countries, that portrays doing things out of the ordinary, being overtly personally ambitious, or not conforming, as unworthy and inappropriate."
What it actually boils down to in practice is that people will try to keep you down if you do good things that make other people look bad, especially if you have the audacity of taking credit for it.
