Which problem you think #Bitcoin cannot solve?
Bad feelings if you stub your toe on the corner of the table? Car got broken after hitting it to concrete wall?
If thinking problems like that, you're correct, Bitcoin doesn't solve them.

Not sure if you really want to know after that great comment, but No, I mean thinks like hate, greed, jealousy, scams, conflicts, crimes, peoples opinion and behavior regarding privacy, politics, populism…
Hate, greed and jealousness are tendencies of human beings, they're what makes humans, human, they can cause problems but they're not problems itself.
Bitcoin will definitely fix most of the scams, conflicts, crimes and politics.
