Interestingly the family model of before the end of WW2 had children stay with their family longer. Well into their twenties and early thirties before marrying and moving out. The post war years saw a change towards earlier independence - it's not hard to see why. Economic and social conditions are bringing back what existed before.
Regardless, the population shift from rural to urban is clear and undeniable. Young folks are voting with their feet and leaving for the opportunities offered in the cities. If the CAF wants to be connected to the general population then it needs to readjust itself to their lifestyle model - a job with a decent salary, opportunities for advancement, a stable job for their spouse, the ability to remain closely connected to their wider, extended family. To quote an old saying: "if the mountain won't come to Mohammed . . ."
I've proposed "urban battalions" and a hybrid unit structure that leverages full-time and part-time personnel. The argument that we don't have a training base next door just doesn't cut it anymore. We need to plan for a system that not only takes in new recruits - and does so efficiently and quickly - but also one that ensures that we do not lose our critical middle offr and NCM leadership because of lifestyle dissatisfaction. The CAF can adjust to a distributed urban battalion system and still turn out well trained units; it can't adjust to a population that finds the current mode of lifestyle inadequate and has many other options available to them.
