In general (and blogs are not a good source of unbiased views on this) the majority of people like their jobs and do feel like they’re using their abilities.
But you'd expect people to like their jobs, partly because of selection effects - if you don't love it, leave it - and partly because people adapt to their circumstances. Given these tendencies, what's remarkable is just how little job satisfaction there is, especially in the sort of jobs are people are supposed to use lots of talent.
This survey of workers in the City - jobs where Daniel says "you are basically able to do as much as you’re capable of (ie to use all your talents)" - reports that only two in five workers say they are satisfied with their work, suggesting widespread unhappiness at how their abilities are being used.
But this is not the only evidence. "Boreout" is widespread , as is time-wasting, suggesting a vast under-usage of talent.
And this paper, and this, suggests that around a third of graduate workers are over-educated in the UK. Evidence (pdf) from continental Europe - where there are more graduates - suggests the problem is even greater there.
And this is not to mention the evidence of our own eyes.
So, surely, wasted talent is not confined to Taylorite-Fordist factories. It's still with us.
This is not, however, to be too damning. Market capitalism is far better at developing people's potential than what Marx called "the idiocy of rural life" - not least because it's good at delivering goods such as software, music and literature that require consumption capital. All I'm saying is that it's just silly to believe that an economy can make the full use of people's talents.
