I think the hardfork has messed up the inflation rate and now we have hyperinflation.  Also, maybe limit voting so you can't vote for yourself and, like you say, an upper reward limit. Some people are earning $000's a day without an income stream other than new investors. That is a ponzi if ever I've seen one. It'll end badly when people realise the steem price starts to drop again. The only reason it has risen is, imho, because all cryptos are in a major bull market.
