Just providing sanitation and water for the masses is not a solution. Must be a comprehensive plan, or they will overpopulate at an even worse pace.
Only the best socialist govt can do keep things this screwed up.
Re: over population
That’s what Africa is for
I remember seeing photos of a public toilet somewhere in Africa, think it was South Africa. It was on the side walk in the open though there was a curtain rod, but no curtain on it. You can give people things, yet fixing ignorance (aka lack of knowledge) can be more difficult. You have toilets, you need septic systems, you need plumbers to maintain them, etc.
