Vicente Fox strikes me as an opportunist; not an idealist. He correctly sees the large scale discontent with the status quo- most Mexicans realize that they are getting shafted; they just don't know how. He has used that widespread discontent to propel himself and his allies into political power. Once in power, they make enough changes to convince the voters that they are doing something to "fix things". Because most Mexicans don't quite realize what's actually wrong, they have no idea that Fox's "fixes" are fixes in the boxing sense and not the repair sense. If Fox makes the discontent go away, then he eliminates the rationale he used to convince people to support him.
In a nutshell, Fox will do enough to make people think he's a reformer but not enough to solve any real problems. The result: new sign out front; business as usual inside.
Well the Mexicans can vote Fox out of office next year if he doesn't "get 'er dun" by then...
but it's time for Mexico to take off the "training wheels"!
