you fail to cover more than 90% of the jobs that just need to be done, and require 0 or less creativity.
as an example - what I do to earn money, while enjoying it mildly as abstractly creative process (software development) is vastly different from what I do in my free time (mountaineering, travelling, general wilderness adventures). You cannot buy my vote on this with some basic 1000 USD income, if you tax high earners like hell on the other side.
One thing I saw consistently all around the globe - people need motivation to give their best and try hard, only few deliver without it for sheer pleasure. It doesn't have to be monetary one, but this one is universal and quite well oiled principle. BI doesn't offer me anything - I want to work, I don't have an issue finding next job, and if there is anything between, we have working social system that helps me. What does BI offer to somebody like me?
