The framing of linking suffering to a personal failing is a mistake. No one “deserves” to be homeless or to go hungry. You can be an asshole, or even a criminal, and you still deserve to have your basic needs met. Maybe you won’t be an asshole if you’re not hungry and can receive mental health care.
I don’t think I have anything to recommend that isn’t a fairly common home tool in the U.S.
Nice sets of metric and imperial wrenches, and at least one adjustable crescent wrench. You’ll use the wrenches all the time, and at a basic level you can get away with just an adjustable crescent wrench. Fixed wrenches are much nicer to use, and it’s super useful to be able to use a fixed wrench and the adjustable wrench for those bolts where neither end is fixed.
A flat pry bar. It’s definitely not necessary, but I find them really helpful. It’s much easier to remove nails than the claw on a hammer, and it’s really helpful for applying leverage in a variety of situations.
A circular saw, chop saw, or table saw. A powered saw is another extremely helpful tool, but you don’t need all three of these. Most people should pick one and I’d prioritize them for in this order.
Random orbit sander. Sanding by hand takes forever and it just sucks. If you use it even once it will have been worth the purchase.
Battery powered shop lights, from whatever brand you’ve bought power tools from. Having a handful of lights you can move to anyplace you need them is really helpful. I think every tool maker these days also makes something like this, just buy the ones you already have batteries for.
Shopvac. Immensely helpful for cleaning up the dust and crap created whenever you working on the house. You can integrate them into most of your power tools (might need some adapters) so that you’re working cleaner, and you won’t burn it out like you could with a household vacuum.
