Honestly?
One has to wonder why some people can see the forest, and others can only see foliage in the way. For someone who "hates idiots", have you ever considered that if you think in the paradigm all the time, you will keep what you have? Maybe those "elderly" get put in PODs, and the POD is moved up and down. Or ??? If we get superconductors that can work at 100 C, then virtually anything is possible in terms of the track. Don't poop on ideas just because your limited view has them not working.
