Re: Keynes, I think we're both right. He seemed to view increased leisure (discretionary time) as an objective good and idleness (the wasting of leisure) as a worrying problem. This becomes clear in the context of his full essay , which is definitely worth a read.
"Reduce inequality in income distribution" is the easiest solution that comes to mind with this respect, however I think that is is not the real problem.
In truth, we are getting to the time where there will be too many people for the amount of work required by the whole humankind to possibly satisfy its needs. We should all embrace this new reality and think of a way in which people can live without working, or in other word, we should solve the economic problem .
Have a look at what Keynes wrote in 1930. "Economic Possibilities for Our Grandchildren." http://www.econ.yale.edu/smith/econ116a/keynes1.pdf
Here are 7 pages which you may have already read, but may even still wish to read again while considering ideas such as UBI; especially if you are a critic of such things.
By Keynes' estimation, those who are discussing such things right now are right on schedule.
