You get to keep only enough to maintain a very modest lifestyle in a low-cost-of-living area, the rest of it has to go towards improving the world in some way.
Edit: Given the previous rules that you must maintain a very modest lifestyle in a low-cost-of-living area, would you rather choose to opt out and not have the money at all?
I guess I’d better hire someone to help educate me about fundraising, tax and other applicable laws, because establishing a (pre?)k-12 private school with above-standard education, three nutritiously sound meals/day, built-in well/sick/before/after school care, extracurricular activities and free clinic with it’s own free pharmacy, both to be offered to low-income community that will last generations is going to be expensive. Plus I’d imagine a team of attorneys on retainer being necessary is foreseeable, if capitalism is still a thing.
That’s at most only 5-10% of 5 billion
What? Land, surveys, taxes, permits, land-use studies, environmental impact studies, architects, engineers, living wage construction workers, materials, faculty, staff, doctors, pharmaciststs, care providers, business, health, property, other insurances, dieticians, meals, maintenance…I want these things funded for centuries. May as well include uniforms, so parents don’t come out of pocket, lawyers, potential lawsuits…5 bn isn’t going to last long.
