I don’t think “how will you pay for this” is the most effective response, as that implies that these are worthy goals if only we had a way to fund them.
I think the better response is - Don’t you know what happens when you remove the incentive for people to earn money by simply giving it away? I’d suggest taking an introductory economics class, or perhaps just reading up on the news out of Venezuela over the last couple of years, before you promote policies that are certain to do the greatest harm to the very people that you supposedly want to help.
When two wolves and a sheep are discussing who is for dinner, economic theory is not persuasive. :-(
