The only way your brother could be right is if you are buying Snap-On tools and boxes and tools when you can barely squeek by with the rest of your bills and he is concerned for you and your family because of your excessive spending habits and he loves you as a Brother.
This is purely hypothetical though because I don't know your situation, but I have have seen it before where I had family members putting their family at risk because of idiotic spending habits.
They would not listen to siblings who were concerned for their kids well being because Mom or Dad was a fiscal basket case.
I have a Brother that is the same way.
He spends like a drunken sailor, and gets mad as hell when anyone questions his spending habits, and he says nasty things to anyone who dares question him so nobody dares question him anymore, but when he calls complaining about his next divorce over money problems, we just say, "Man, that sucks."
I mean, what can you say to that?
I guess some people would rather have the best of the best even though they can't afford it, and they know it will all come crashing to an ugly end sooner or later as was the case with my Brother, and several other family members.
All that being said, if you CAN afford it and have no issues with money then , yes, your Brother is jealous and needs to get some financial advice from you.....LOL.
I can attest to being on the opposite side of the spectrum with tool boxes.
I got ragged on all the time at the dealerships I worked for having sissy craftsman boxes instead of the high dollar snap-on boxes.
I had alot of Snap-On tools which was enough for me.
It was funny because when the Snap-On guy came by, alot of the guys that ragged on me would cringe, and sometimes give reasons why they could not pay the tool guy this week because of other bills mounting and if I was in the snap on truck with them during the payment I would rag on them bad about their balance being more than my home mortgage, and then ask them if they wanted to trade for a nice, cheap Craftsman box that does exactly the same thing as a Snap -On box does.
Oooohhh, talk about instant payback. LOL.
