Obviously, providing for own safety is only one facet of independent living. Being able and willing to work, having interpersonal skills to navigate the social environment are other necessary components. Those skills, more than material inheritance, are what caring parents should impart to their kids. These are skills that are taught only slightly or not at all in public schools.
In fact, public schools are trying to eradicate not just the ability for self-defense but the mere thought of it. Brainwashing in the form of capricious, random enforcement of completely crazy, fetishistic rules against any kind of effective defensive tool, technique or even a mention of the Constitutional right to bear arms isn’t applied for the benefit of the students. It’s designed, consciously or not, to foster learned helplessness and dependency on authorities. Psychiatric treatment is then forced onto the kids who are merely reacting to a very unreasonable environment.
Of course, some inherited capital helps because it allows much quicker transition to full independence. This is exactly why the inheritance tax is one of the many ploys to foster dependency on government handouts. Instead of parents being able to help their kids, they lose funds to taxation and the government then doles out a small portion back — which always comes with string attached.
As an aside, I’d rather have this home-schooled teenager on my team than any number of adults. Riflecraft is just one of her many skills.
