I feel like I'm constantly explaining how unconditional basic income is money to do anything, not nothing, whereas typical welfare programs create an incentive to keep one's income low to keep qualifying for the benefit.
With UBI, everyone is always better off working than not.
An experiment in Spain looked at the different impacts on work that welfare with a 100% marginal tax rate has compared to a UBI with a 20% MTR, and the results were quite revealing.
They should also be obvious though.
