The idea that one can make a sacrifice to assure future success is ancient among humans, isn't it?
Deprivation doesn't create appreciation. It creates some or all of desire, neediness, curiosity, fascination, resentment, obsession, anger...
Unfortunately the real sacrifice parents make too often is their child's happiness and their own hope of a full and healthy relationship with that child and future adult.
