Do you think that younger people of today have less family values ?

You would actually have to define "family values" for a real answer. The term is one of the most abused sayings in the political arena. If you look at the United States and consider who bleats the most about the mythical family values (Republicans) and then consider who exhibits behaviour that would be contrary to the basic idea (also Republicans) then you pretty much have to come to the conclusion that there is no such thing as standardized family values.
