My advice is: invest money into better law enforcement, including ML and AI-based, like crime prediction and drones. Make sure, by a combination of legislative and informal methods, that poor and well to do communities are better separated from each other. Invest more in stuff which gives poor people something to fill their time with, like video games, so they don't do as much crime. And that's it.
Why not invest money in education, training and a social security net that gives poorer individuals the means and space to catapult themselves into wealth?
