In 30 years they'll be a huge liability for the state. In the past, they used to send them to meat grinders (wars). Somehow later it was figured out that a mandatory cut of their paycheck will give them a small payment later in their retirement years. But now that social security is broken (both in the US and Europe) and short-term thinking is the norm, every "business men" is salivating at the opportunity.

In a couple decades, they'll be a massive drag on society and could even collapse countries. France is kind of a good example of how that future will look like.
