I think many people go "full circle" and end up becoming disenchanted about the lottery of eating out and learn to produce excellent food at home.
It also seems to me that the best food often seems to be the food provided to working people on the streets - as an earlier poster said - hawker food in Singapore being an example.
In my view if you are fortunate enough to buy in fine dining restaurants then spending cash on extraordinary ingredients prepeared with love and care at home is worth the learning of how to cook well.
