Yes, it is completely possible that today's 99% are tomorrow's 1%. It's actually very likely... if Steemit matches the market cap of Facebook, 1 STEEM = ~ $3500 USD. So the 70,000 or so users that are here today would become the new wealthy elite, and those that join Steemit in five years will consider wealth distribution to be unfair. Kinda like the baby boomers and the millenials...
