This exactly. A new form of currency is not going to solve the world's problems when the people with the power to make change can't or won't exercise that power.
I would not be surprised if an article pops up saying that Bitcoins intention to end poverty failed. 
The short and only answer is no, bitcoin will not help to solve world poverty problem. Why? Because economical systems, regulations and laws are not the problem here. Humans are. People are so corrupt and flawed that they do not care about making this world a better place, they just care about themselves. That is why we will never have world without poverty, wars and terrorism. Bitcoin is nice tool but it is people who will be using it. That is the problem.
IMO"Corrupt" that is the problem, in my country there is so many corruption.
So with BTCitcoin we can see all of the people transactions, so we can easily find the people who corrupt state money.
85 richest people have as much money as the 3.5 Billion poorest:

The whole system is flawed. Donating money to feed people doesn't do anything but help them survive another day. Bitcoin can't help here.
