Oh absolutely agree, everything up until now has eventually descended into the age old pattern of power and money finding it's way concentrated into the hands of the few elite, however capitalism with it's private ownership of the means of production and their operation for profit, and rewarding accumulation of capital, seems like it's designed from the ground up to funnel money and power into the hands of the few, where at at least in theory communism/socialism/other -isms are designed to try to share the wealth.
Of course, said -isms require either an unbroken chain of morally righteous people with absolute power being in charge of said means of production fairly for the equal enrichment of everyone, or some kind of system of checks and balances to keep those in power from abusing it and preventing corruption from outside the political power structures, the exact formula of which we've yet to figure out.
Personally I'm of the opinion we should just throw the baby out with the bathwater and chalk this whole civilization experiment up as a mistake and go back to tribal societies of yestermillennia. Of course, the vast majority of the current human population disagrees with me in that regard and I will admit there are some good things about it, so until that changes I'll be here plugging along like the rest and hoping for better days.
