It's such a small amount of money per person that it is hard to see what effects one would expect. I think for the majority of people reading hacker news $1000 per month would be barely noticeable in their bank account (obviously some people out there would notice it, but for say a lowly software dev making $150k it's not going to change much about their lifestyle). So to think it would fundamentally change someones life is a stretch. I mean it's not enough to not have to earn money (and so have the financial security to start a company or restart education) and it's not enough to purchase accommodation (especially cause it's limited to 3 years). Most I would expect is people could pay down some of their debt - so they can tread water a little easier for a few years.
