I really hope they introduce a year of social service. No matter if military, police or healthcare, everyone should experience what it feels to serve society at least once.
An interesting aspect I didn't think of so far was recently brought by German news influencer LeFloid: It adds people to the mix of police and military that wouldn't normally be there. The far-left tend to avoid them, while the far-right embraces them. This creates a dangerous imbalance between left and right views in these structures and opens up room for radicalisation.
