If you've missed previous opportunities to tell your Congressfolk to pass H.R. 860/S. 269, the Social Security 2100 Act, then Social Security Works still helps you do that. The Social Security 2100 Act would increase benefits, shield more Social Security income from taxation, and start taxing income above $400,000 into the system. If you want, though, you could tell your Congressfolk to improve the bill -- there's no reason income above $137,700 and below $400,000 should be untaxed, and there's no reason we should tax anyone's Social Security income at all. You might also mention (there's a "comments" section for this at the above link) that you oppose bills like the so-called TRUST Act, which would let Congressfolk fast-track Social Security cuts "behind closed doors" (in Sen. Ernst's words, which I sincerely hope she regrets after Election Day). We might as well demand the most, or else we'll have to live with the least.
Meanwhile, H.R. 535/S. 618, the PFAS Action Act, would require our EPA to designate all PFAS substances as hazardous; this shouldn't be a tough lift for our EPA, not just because a) PFAS chemicals hardly degrade over time and b) scientists have linked them to cancer, immunity disorders, birth defects, and liver problems, but because our EPA has long acknowledged the need for action on PFAS chemicals -- in fact, they announced a plan to deal with PFAS chemicals just last year, a plan widely derided as too-little-too-late, but it's not like they're going around calling PFAS chemicals "safe." You know, like our President goes around calling climate change a "Chinese hoax" and wind power "dirty"! So Food and Water Action helps you tell your Congressfolk to protect our health by passing the PFAS Action Act. If it's in everything (and it is), and it doesn't break down naturally, then it's in our water, too -- at least, it is in 43 states, that's 43 of 50 -- and if we don't have clean water, we don't have health care, period.
