I agree something needs to be done. I also agree with the long term view, not the short term. My concern with a fixed amount per block would be the possibility that it would encourage people to have lots of very small blocks vs. the incentive now to consolidate blocks occasionally to improve performance. Perhaps a very low % vs. a fixed amount?

Thanks for the comments Fred,
We would have to go down to
0.0005% (0.000005) per year,
that would leave us only gaining ~ 180,000 new coins per year (basically ~15000 new coins per month).
I imagine , if we did change the % that low, we would not need to changes any other specs.
As your amount earned per block would still depend on your amount in the block.
Does dropping to
0.0005% per year appeal to everyone more, than the fixed amount that would require the additional changes in minimum stake age?

FYI:
From Marketing aspect after the Change, if everyone agrees,
we could list
ZEIT as an Ultra Low Inflation Coin.
