Maybe SS/Medicare aren't entitlements in the pure sense
We do pay into them, but when the program was designed, it wasn't meant to sustain people for 20 or 30 years. Life expectancies today are much greater than in the past. There were more people paying into the system in the past as well. This has caused a shortfall in our obligations and its only going to get worse if they don't find a way to fix the program.
