From a piece in the New Yorker about The Ford Foundation (lightly edited on my part):
The urge to change the world is normally thwarted by a near-insurmountable barricade of obstacles: failure of imagination, failure of courage, bad governments, bad planning, incompetence, corruption, fecklessness, the laws of nations, the laws of physics, the weight of history, inertia of all sorts, psychological unsuitability on the part of the would-be changer, the resistance of people who would lose from the change, the resistance of people who would benefit from it, the seduction of activities other than world-changing, lack of practical knowledge, lack of political skill, and lack of money.
Lack of money is a stubborn obstacle, but not as hopelessly unyielding as some of the others.
The above was written in the context social justice, but much of the paradox in this article translates to business too. While lack of money can certainly screw you up, it's more common to fail because of the multitude of other factors working against you - many of which are *far* more difficult to overcome than lack of money.
