Hypocrisy of Buddhism Aren't Buddhists (with Buddhist I refer to an ideal Buddhist or Buddhists monk) actually not doing enough to prevent harm in this world?

So, Buddhists don't have any attachment to things and work towards reduction of suffering in the world. Given the focus and discipline dedicated Buddhist has, they could use this to become successful businessmen for example and use that money/power to help people. But many don't, they seem very passive from what I have read so far.

In a sense Buddhist not trying to accumulate money/power and use it to help people and change world, is hypocritical?
Buddhist master, Ajahn Brahm, answered a similar question as follows in an interview with Rachael Kohn:


  Rachael Kohn: I know that your message is often about happiness, and how the point of life...is all about changing one’s attitude, not
  really about changing the world. And yet you would know that that kind
  of an attitude can also be breeding a certain indifference to the
  world...Does Buddhism ever teach a resistance to things which are
  dangerous, which are bad, which are evil?
  
  Ajahn Brahmavamso: Yes, we teach a resistance to anger, we teach a resistance to jealousies, we teach a resistance to stupidity. Those
  are the things which we should really be resisting, you know, the
  anger and the feelings of revenge, the hurt, the grief, the guilt
  inside of us, all those negative emotions which make our world. Those
  are the things which we want to resist, to understand, to overcome, by
  letting go.


In other words, Buddhists claim that harm in this world arises because of greed, hatred, and delusion; they seek to eliminate these sources of harm within themselves and to educate others so that they may do the same. So, on this view, Buddhists are addressing the root causes of suffering in themselves and others and helping people in this way--the most effective way. As the passage above implies, an ideal Buddhist is far from passive internally and, although she may appear to be so externally, one could argue that she is simply skillful/technical in her approach to the suffering of others.

In summary, Buddhists want to use wisdom, rather than money and power, to help others. According to them, this is the most effective way to do so, and the only way to get to the cause of the problem; using power and money to alleviate worldly problems can be a temporary, palliative solution at best. The Buddha often compared himself to a doctor, treating the causes of suffering rather than exclusively treating the symptoms.
