As I understand it, the UBI is paid to everyone from the homeless to Warren Buffet and Bill Gates.  That means the total cost of the UBI is for the entire population.  Currently, only a fraction of the population receives welfare from those "126 agencies."  Would the UBI also end the need for social security?  If so, will I get all of my money back?  If we do give folks a lump sum each month/every two weeks does that mean government has no role in how one spends it?  For instance, if a mother and/or father decide to go to Hawaii at the expense of housing/food for their family, so be it?  Additionally, what is my incentive to work and where does the tax money come from to pay the UBI if nobody works or why should I work to pay for others not working?
