Building a kit radio is no assurance that the person will be enlightened as to how a radio works; it will either prove they can solder correctly and read instructions - or not.
Tolerance for those who have not made electronics their career and requiring them to understand much in order to have access to the airwaves is really the question some Hams pose. A CBer merely slaps some wires together with an antenna and a radio without a license and can do it. A kid can get some walkie-talkies for his birthday and can do it too. Almost everybody uses a cell phone and by proxy are doing the same thing.
Yet we expect and demand that Hams be enlightened - or go home. While there is much in the middle that is being held back to make A reach B. Less Elmering and more criticism will never reach the desired end. That is a formula for frustration on both sides. Or, it can be treated as a hobby; as that is what it was meant to be.
People are either cheap or they have too much money and don't care.
