You'd have to tilt a lot more than what Germany does to make it worth it; equivalent healthcare in the US is only €15k in additional costs. (The messy healthcare situation the US is famous for only really affects the poor.)
It only _directly_ affects the poor- regardless of whether I as can afford these things, it benefits me to live in a society where everyone (including "the poor") is educated to a high standard, is not living in fear of financial distress due to minor illness, and is able to pursue their vocations out of choice rather than necessity
