I'm not going to pretend that some people don't thrive when looking at the poverty void -- they are the exception to the rule. There are also those who coast on gov't funding. There's probably many reasons why someone would coast, but if I'm in a system that has so thoroughly forgotten about me since birth (e.g. not having any opportunities for better education for one), why would I want to partake in it? I think the cost of a few people not trying to make changes for the better is by far outweighed by helping those you need support in their most desperate time.
It's not about giving people a safety net when the have moonshot ideas to start a business. It's to have a safety net when they need a bit of time to improve themselves, which when you have little time and money is a huge risk.
I think there's another factor to consider. W doesn't give water directly to P, there's G who takes a little bit of water from everyone. G has enough water for themselves, and instead of drinking just the water they need, or helping U to make their island economy better, they decide to bathe in the water. Then when P wants some water like G has promised and there's none left, they blame U. Which makes W and P angry at U.
The situation is more like G is taking a little bit of water from everyone, and there's yet another person on the island E. E is in charge of delegating coconut fetching tasks to W and up until recently P. G decided E should also be in charge of distributing water that comes from G to W and P.
E realizes that once P leaves, there will only be one coconut fetcher. So, worried that they won't be getting enough water to give to G, E gives less water to W instead of hiring and training U to help this coconut fetching business. This isn't good because eventually W will become a P, and E will have no one, and G will not be getting water from E. Everyone becomes a U because G decided to give water to E to delegate instead of directly to W, P, and U.
