We cannot expect the school system to solve every social issue. If what you have found is a general trend then it is a failure of the Political Parties.They are obviously not reaching the young people.

Also our "two Party system" has deteriorated to a level at which "rubbishing the other team" is more important than the future of Australia. The Parties do not present an image worth emulating or worthy of following. Both sides (and even the Greens) are more interested in tearing down the others than they are in building Australia.
Individual politicians are mostly great people, but the group is damaging our democracy.
