I know a guy that would go to Haiti every year and teach them how to build wells and then get the water into pipes to bring to various areas of the villages.
He would install one well and pipes to educate a group of locals, and then leave enough supplies for them to complete numerous other projects. I think he gave up after the third year. The supplies he had left had been sold so the group could buy stuff, and the pipes he had installed were torn up and sold too.
He then started setting up cell-phone and internet instead. He said that lasted longer. One - the people got entertainment. Two - the government had stiff penalties on tampering with it. The government used it to get its propaganda across, as well as keeping tabs on people.
For countries, like Haiti, they need a benevolent dictator to manage them until they heal enough to improve enough to be self governing. That goes against my principles, but they are on their way to extinguishment otherwise.
I know a lady that os there 90%of the year trying to help them. She’s been doing it for years and it’s no better now than it was then. Until the people get up the gumption to change the country, it won’t change. Same goes here anymore
