Should not make fun of others, but you need to check his papers: did he graduate from UTI or with UTI (Urinary Tract Infection)?
It's quite strange that a person can go through tech school and have no tools. I am a DIY (not much, but slowly learning) , but even I accumulated some basic tools fixing little things in the car around the house. However, the circumstances are different for every one of us. If he is not a complete ***, may be he needs some help and guidance. I noticed that a lot of people who keep bragging about their schools and diplomas are not so good at what they do. The ones who are really good do not need self advertisement.
I would talk to him and try to understand his situation. If he is a normal person and just hit the hard times and is depressed and keeps making mistakes because he is too nervous and not paying attention, teach him.
When working and controlling much less experienced members of the teams I used to do the following: during morning plan I would ask everybody to get a piece of paper and on the left make a small square and on the right wright a task. As the day goes through, put check marks in the boxes to know you finished it and add new tasks at the bottom. Works well for majority of people (I still use this system if I have to do a lot of things and do not want to miss anything)
About the tools - give the guy a basic idea of how to acquire tools inexpensively (Craigslist, yard sales, etc). Some of young people are clueless. There are good deals to be had out there. I recently sold a set of 11 SK SAE sockets and PROTO flex extension (1/2 drive, almost new with some never used, but marked) to a young guy for $35 (I got an older unmarked set for relatively little money, decided to keep that one). SK ratchets can be seen on CL at 10-20$ used, etc... Wrenches can be had for little money (especially SAE). As he learns more, earns more and knows what he needs, he can start replacing cheaper tools with Snap On, etc...
He also needs some explanation about asking to borrow tools: we all need to borrow sometimes, but if you are in professional setting certain amount of basic tools is expected. I do not mind letting people borrow tools if it's reasonable (though I do not like giving my Snap On honestly....) - nobody can have everything and some tools are not worth buying if you do not use them often.
He might be an idiot or he might be a person who might need a hand when life is hard. I had multiples of both in my life. The first ones will never appreciate whatever you do for them, the second ones with some luck get better and try to help others as well...
