Culture is set from the top.
Many of football's administrators are incompetent buffoons who fail (or are very slow) to address the big decisions or get them right, yet they revel in their status and love to intervene and throw their weight around on trivial matters that don't really matter.
It is therefore little surprise that the people they appoint to oversee the game on the pitch display the same broad traits. They haven't got it right at Premier League level where the financial stakes are huge, so by the time you reach League Two level you're lucky if you get someone who has the basic levels of knowledge and physical fitness required.
The playing side of the game has become ultra-professional, what with sports scientists, data analysis and everything else, yet the officiating side is only gradually crawling out of the dark ages. The obvious evidence of this that the use of technology to increase the number of correct decisions is still seen as an issue to be "debated", while other sports took the lead in bringing in such measures ten or even 20 years ago.
