I think, of the many points of attack in leveling the playing field, removing regulations that prevent small-time "investors" from owning equity in ventures is a candidate that's high on my list.
Although in a way that passes the buck (ie. you're still dependent on investors and giving away equity). I am looking forward to seeing how crowd-sourced loans and such will work. For example imagine a prosper.com at scale (catered specifically toward small business loans).
And wouldn't it be nice if regulations didn't prevent a small startup from creating such a crowd-sourced loan program?
How about a crowd-funded VC platform? I imagine alot of things are in the works that will help reduce the importance of the middle-man (ie. the investor). I look forward to seeing how that all comes together. But none of it will get off the ground until regulations are no longer the barrier to entry.
