And why should tinkering be easy ? The whole point of it is understanding things beyond the initial use and this is the mindset that, I believe, only handful of people have (like one in ten). I distinctly remember that when I was tinkering in high school with things most of my peers were tinkering with people (a.k.a living life). So maybe, just maybe, it does not really matter if tinkering is easy or not - because its mostly character that decides if You will be into it or not (I subscribe more to nature then nurture side).

And I honestly question if my children should waste their life on things instead of people.
