All across the US, if you are younger, you likely get less compensation than if you are older. Older union members vote for higher compensation for themselves and reduced compensation for young and future union members, since they cannot vote. For example, if you look up collective bargaining agreements, you will often see tier 1 benefits for employees hired before year x, tier 2 benefits for before year y, and tier 3 benefits for after year y, etc.
A similar dynamic plays out with taxpayer funded benefits and older voters vs younger voters.
The US has an “Additional Medicare Tax”, to help pay for healthcare for older people. But there is no “Additional Medicaid Tax”, to help pay for healthcare for poorer/younger people.
