There are many issues like this. The biggest change that would happen to islamise a society would be the education sytem. Use that effectively with a good dose of quraan and hadeeth and tarbiyah and half the problems would be solved. Also like imam hasan al banna rh said change office hours so banks etc open straight after fajr so people go sleep early wake up for fajr and do work early etc. There are many such examples
