Its easy to complain but the reality of what your demanding is that many more elderly citizens should be unable to afford their homes and be forced out of them. That's not a preventable side effect, that's the desired outcome. It seems obvious to me why many don't think that's ideal.

If opponents of prop 13 want it repealed they're going to have to buy out existing homeowners to get the votes. I won't pretend to know what that would take but you won't get the moral high ground with a straight repeal so you might as think of some sugar coating.
