I was thinking more in terms of there ability to strongly convince the average American to step away from the likes of Chase,BofA, Wells Fargo etc. If the average joe sees the flaws in the current setup but does not see a realistic alternative then they are likely to maintain a relationship with those who represent the status quo. That would entail focusing in on consumers having more options as it relates specifically to financial services.
Well, this is exactly the problem. When people talk, for example, about companies being too big to fail, they're right in one sense- most commodities (including services) are produced primarily by only 3 or 4 massive corporations per commodity, resulting in serious disasters with immense waves of impact should they go down. They should never have been allowed to grow to that size in the first place.
Furthermore, they function (sometimes intentionally, sometimes not) in collusion, not actual competition. There is total transparency between them (and thus no "invisible hand" which, in theory, is the motivator of prices, etc, in a free market.) The result is a market that is anything but free, in which these corporations set prices rather than organically deriving them from real market fluctuation, and there is nothing competition can do to legitimately offer alternatives. In short, creating actual opportunity for small businesses, which amounts to freeing up the market again, cannot be done without limiting these corporations, which points to the contradiction inherent in a great deal of free market economics.
Unfortunately, most "free market" theory is not equipped to do this, nor are most prominent proponents of free markets able to speak in these terms, since it demands an honest paradigm shift, in which the most basic terms like "free" and "market" and "capitalism" would be overhauled.
