The top 0.1% in the US have ~20Trillion in wealth. That's enough for all ~340million Americans to get 58,000. Globally across all ~10Billion people thats enough for everyone to get 2,000. That's a one time thing, making it an investment isn't accurate to what it represents in terms of value generated that was not given to the workers.
At the US level 58k would get most people out of student loan debt (29k average)and free from credit card debt(6k average).
At a global level 2,000 would allow the world's poor to be able to eat a healthy diet(3.54) every day for over 1.5 years or a subsistence diet (0.83) for 6.6 years
