You state: "We are our own enemies here. We are doing this to ourselves. The curation is supposed to reward meaningful content as the goal in the white paper. But, most influx of users are focused on themselves and making money, not on helping the quality success of Steemit"

I agree, but I fear that this is a tough battle. This is an example of what in economics is called a prisoners dilemma. If the system is such that actions which are detrimental to the society will benefit the individual, than the society will lose.

Look around you and see In how many environmental issues this is the case, and not just environmental,...

Personally I try not to care about the money. I try to write good content, engage in meaningfull discusssions and if I make a couple of cents or a dollar, all the better.

In the long run, I am confident that steem will stabilise. The lower the value goes, the less "quick buck artists" will be out there, and the less the monetary value of a boob post will be. From there on, it can begin to move ahead again. (that being said, like everyone, I would like steem to rise to the moon, for which we need a gigh quality community)
