Also is having twice as much money (1x from interest and 1x from income) not a benefit?
Maybe you are the strawman consumer that skeptics point to in guaranteed basic income debates, who just stops working because they get a check.
The only thing I want to spend a bunch of extra money on is a nice property and making twice the money would not get me there in what I consider a reasonable amount of time. I'm also not interested in going on an extra two fancy vacations per year or a nicer car. I'm plenty content to read, cook, learn, and enjoy the arts.
If the first 1x covers all your spending, what else are you going do with the other 1x? Invest it in even more investments to produce more income that you already cannot spend? That turns into what is essentially working for free. Why bother?
