High population is a major factor, always neglected when these (also popular in Germany) Sweden/Scandinavia Socialist Utopia comparisons are made.
But there is more to it. Very unequal distribution of wealth must also be tackled, as it is a major contributor for people to do illegal things. Another question is if prison sentences are not too long and harsh. Given some documentaries I have seen they also seem to fail hard at resocializing "criminals". Many are not THAT criminal, but there is a danger they become notorious criminals after being in a prison for too long.
But well, I will now rather focus on what to do against German Gerontocracy and the fact that the only major opposition party (SPD) usually forms a coalition with the CDU since Angela Merkel is in charge. The other parties are too weak to have much influence and Merkel manages to shift blame on the ministers of her coalition partner. But well, I still don't get it. She is too long in office already and there is no limit how often a chancellor can get re-elected. Ugh...
Maybe an autonomous orbital platform could solve that problem?! :P
