Every so often a new study is released, concluding that a universal basic income (UBI) is needed to fix this country’s welfare system. Most recently, the Roosevelt Institute claimed that switching to a UBI system could actually grow the economy by $2.5 trillion by the year 2025.

The study is full of hypothetical situations in which Americans receive a UBI of varying amounts. The research concludes that the higher the UBI, the more prosperous the economy. But like many UBI apologists, the study misses the major problems with such a system. Here are the three main ones:

1. It’s Expensive

Proponents claim that the UBI would be an efficient replacement for the country’s bloated welfare apparatus, and so would actually reduce overall costs.

Unfortunately, a welfare state by any other name is still a welfare state. And the UBI is just replacing one pricey system for another. And unlike the current welfare state, which has standards for determining who qualifies for certain aid, a UBI would be given to everyone. This would dramatically increase the pool of citizens receiving benefits from the state and inflict massive expenses across the board.

The Roosevelt Institute study posits two different ways to fund the UBI. But neither would benefit the national economy or the taxpayer. The study’s “positive” findings about economic stimulation are only applicable if the program is funded by increasing the federal deficit. So basically, in order to “grow” our economy, we must first plunge the American people even further into debt.

The second scenario presented in the report was a UBI funded through increased taxation. In this instance, the study found no net benefit to the overall national economy. In fact the report even went so far as to state:

When paying for the policy by increasing taxes on households rather than paying for the policy with debt, the policy is not expansionary. In effect, it is giving to households with one hand what it is taking away with the other. There is no net effect.”
