>In reality it does mean giving away a % of earnings
Not necessarily. Part of the reason for this research is figuring what to do if the robots replace us for the most part. In that situation wages would likely be low and a lot of the value would move to the market cap of the leading tech stocks that controlled things. The government could tax that, as cgt or wealth tax or similar, rather than wages.
Right, thanks for clarifying - I had meant earnings of a company as well (or any task that gets done and has a 'profit' associated); perhaps earnings wasn't an appropriate word to for me to use.
