My understanding is that UBI would benefit the impoverished the most, allowing them to get out of debt, put food on the table, or maybe even put a roof over their head, finally opening the door for them to live a prosperous life. This significant change and opportunity for them outweighs the inflation they may face. Food, water, shelter, and healthcare are a human right and UBI is one way to deliver that, so we should probably commit for that reason alone. Those of us that are better off can begrudgingly cope with the inflation potentially created (note: most likely a product of greed). Besides the potential price hikes, we all see a return on investment as a society when our weakest are made stronger.

As for where the money should come from and how to support this change, we need to make the ultra wealthy finally pay their fair share, break up monopolies to create competition and options, and properly punish exploitation.
