I would happily opt out of SS as well as NAR if I could either. Also anytime I get a bill that has an optional lobbying contribution (there is one on my RE organization memberships) I ALWAYS OPT OUT! I own a timeshare which also has an optional contribution to a lobbying organization. Opt out of that also. I do what I can.
Have to laugh about the comment that public sector workers will have to prop up SS even though they get nothing from SS. Thats right, they get theirs from the approximately 30% most of us pay in combined federal, state and local taxes from those of us who pay an additional 7 to 15% toward SS already. Carry on.
