When money comes so easily it will drive up prices. If it's done on a spot level it won't make an impact but once you increase the size of the population that received this free money, it will just drive up prices.
For example look at there mortgage interest deduction. It's purpose was to make home ownership cheaper but what it ends up doing is causing house prices inflation, at least in areas like the bay area. The deduction gets factored into the financial engineering required to figure out how much you can afford to pay for a house, which causes there prices top rise.
The same thing will happen when people get free money every month. Just like how rent prices increased around face book when they offered a subsidy if they lived within 3 miles of HQ, the same type of increase will happen if a larger enough population gets this free money.
