No, it won't. It screwed me up in ways I still haven't fully grasped, and has long term negative consequences in my life. And I certainly wished I had been more mentally prepared to handle its impact.
Which is why is fucking bothers me that you dismiss life for kids in the developed world as an "absence of real problems". Just because we're not scavenging for food, doesn't mean we don't have real problems.
Sure, thankfully many kids won't need that knowledge until they're older, if ever. But it's not always clear who will. My family certainly didn't meet the stereotype.
