I think the countries that have National Service and do it well have reasons for doing it that aren't just because they can't think of another way to solve the problem of disaffected youths.
The problem for the UK is that those other countries have either historically had national service for several generations, or have a particular reason for needing to introduce one.
If I was a youngster today and somebody said, 'look, kids, it's all hands to the pump because we are under threat from our neighbours and our military isn't enough to defend us', then I might say, 'OK, then'. But that's not the situation.
You are right to say Public Service isn't valued. But part of the reason it isn't valued by today's youth is because it hasn't been modelled for them. Nobody under the age of 83 has had to do it. I was born in the 70s and my parents weren't old enough to have done it.
It's a bit hard on them to criticise them for not having a value their parents weren't expected to have. That's the biggest difference between us and other nations. Three generations - Boomers, X and Millennial - haven't had to do it in any way, shape or form.
Whilst I do like the idea of, as in Finland, options that aren't just military for doing a service to the nation, we still have to get past the fact that we're asking them to do something we didn't have to do for no reason other than because we think there's a problem with our young people.
If they aren't what we think they should be, that's on us. The idea of a social contract frankly ended with the boomers. Although I love my boomer parents, they are the typical examples of boomer conservative individualism. Look after your immediate family and sod everyone else.
The young adults today are the product of three generations who have prioritised individual freedom and wealth over cohesive social contractual obligation. We lament the loss of the 'village' but how many of us make the effort to be the village for others?
Sorry, digressed a bit there. I don't disagree wholly with you, I just think we are expecting something from young people nobody expected of us.
