Why should we care about a disincentive to work more? It's like that trope about welfare recipients all being drug addicts. Or that taxing the rich will make them not want to work.
What motivates people to work is MASTERY, AUTONOMY and PURPOSE. This is very different from the profit motive, and is why people contribute to open source and science.

And anyway, why in the 21st century does everyone need to work? Why should wages be the primary mechanism by which living wages trickle down to the plebes?
McDonalds will soon cut its workforce. So will Uber. Thanks to automation.
If you are jealous that someone somewhere is receiving free stuff, realize how much free stuff you have just by being alive in the 21st century!
If you are upset that you'd be taxed for the free stuff -- then make sure that we develop systems to tax machines. Yes you heard me, start taxing the machines.
If people were more free to choose what to do with their time, they'd probably spend more time with their family and study more and contribute more knowledge to society. Instead of working a dead-end job at McDonalds.
