call your parents

The BBC reports about a new “Elderly Rights Law” enacted in China to promote, under pain of fines or jail time, adult children visiting their parents and never neglecting the spiritual and emotional needs of older people. Though a nice message, regulating visits and enforcing the policy maybe such not be something left up to the authorities and perhaps the criticism is somewhat deserved, since there's no equitable way to apply it and no allowance to help keep children in compliance. I miss my parents and family very much but personally don't need legislated guilt to encourage me to make the time. What do you think? Is such a law necessary and do people need this sort of nudge?
