What I say is true. If curators make roughly nothing, then how is Steemit any different than a site like YouTube (only content creators earn)? What's the point in holding SP?
If you want Steem to be an attractive investment, make this so called "Steem Power" actually powerful. Right now it's more like "Steem Weakling", if you ask me.
If, on the other hand, you're glad with a flash in the pan, short time window to cash out on your content before this all collapses in on itself, by all means keep curation as being paid in peanuts for holding a boat-load of SP.
You gotta realize that holding a high amount of SP is a fairly risky thing and it's those very people that have taken this huge risk who're making it possible for these content creators to be paid (in anything more than mere pesos) in the first place! Don't bite the hand that feeds you!
Should all these high SP holders get fed up enough and they all start to sell, guess what happens to the author payouts? Don't be too myopic in how you view this.
