The Defend and Improve Social Security Act of 2018

Since the repubs seemed bent of destroying social security I have come up with an alternate plan. It is something I have been kicking around in my head for awhile and finally put to paper. I plan on sending it to my congressman, but I would like to get DUers input first. Also feel free to send it to your reps also. And if there are any DUers that are really good with numbers please crunch them for me. I have used some online save social security calculators but I could not put all the changes I made into them. The closest I came up with was that this plan would make social security solvent until the 2070s.
