jaja - Find examples of broken cheap tools (in the metal or in photos) and explain why they broke (poor fit, as cockney steve explains very well - or inferior metal, such as carbon steel, instead of CR-V-Mo tool steel).
Request suppliers to provide specific details of their fit tolerances, their steels used, and their company QC methods (how often are their tools inspected during the manufacturing process?).
Explain to beancounters with detailed drawings/photos, how cheap tools have poor design in the amount of offset (for offset tools) - have inadequate thickness of material in crucial points of stress in the tools - how they have poor final finish by way of forging flaws and poor-quality chrome - and how they have poor design of the grip area.
However - there are many moderate-cost tools of Taiwanese origin, that are more than adequate for the job, where they are not placed under extreme stress continually.
Having said that - where tools are regularly working at their stress limit - such as crowfoot bars, hex keys and hex sockets, and cobalt drills, then it pays to purchase the highest quality tool you can buy, without question.
Unfortunately, Snap-On have fallen by the wayside, along with many American tool manufacturers - and they now get tools manufactured on subcontract by the likes of Taiwanese companies - and dare I say it - even Chinese manufacturers.
I have purchased items such as American Vermont cobalt drills, with the packet wearing a highly-visible Stars & Stripes - only to find in tiny print, "Drills made in China - (plastic) box Made in America"!!
