I think that solution could be to pass a law that treats a son and a daughter equally. Son and Daughter(married or unmarried) should be given equal inheritance. Parents can have rights to spend their entire earnings , assets etc. if they want but can't  have rights to give wealth either only to son or daughter. Within few years of implementation of this law, I bet you can witness the sea change in the peoples' behaviour. 

Money is the root cause of all evil. At the same time if one knows how to earn,manage, spend,share and control it , peace and contentment can prevail in every soul. Hence, less problems.
