Existing welfare addresses the problems of unemployment. Not as well as welfare in other English speaking countries, but it still ameliorates the problem.

My position is that even with the current welfare system, technologies that increase productivity, but make some people unemployed, are still good from a utilitarian perspective. The trickle down effect (including through the existing welfare system), which benefits the entire poor population, makes up for the negative effect on the newly unemployed.

EDIT: as always, I have no problem with downvotes for my other opinions, but it's really sad to see downvotes for economic orthodoxy. If anyone reading this downvoted me, please educate yourself on mainstream economic thinking. You don't want to be remembered as an anti-vaccination advocate.
