1. At least in the US, contributions to social security stop once you hit 160k, making it a regressive tax. Raise that cap and like magic, the system is solvent. 2. Growing home prices come from a lack of supply. And you’ve completely flattened an entire generation into one wealth class, which is a gross distortion of the facts.
That doesn't make it "regressive". The untaxed dollars after 160k don't count towards benefits. Rather, the tax is extremely progressive due to the various "bends". As you contribute more into the system, they make the per-dollar value of your contributions go from .9 to .3 to .15. Anyway, Social Security is fine. It's Medicare/Medicaid that's going to nuke the budget.
