In one sense, it is clear that not enough is being done to fight global poverty. This can be seen in the fact that there is still poverty all over the world. It follows, then, that not enough has been done.
The problem with saying this is that we do not really know what needs to be done to end global poverty. Therefore, it is not that we are unwilling to do what it takes to end global poverty. Instead, we simply do not know how to end it.
Simply giving aid to countries often does not work. Those countries are often run by corrupt governments whose members enrich themselves on the aid rather than giving it to the people. Even where aid is distributed, we are not necessarily able to give aid that works to reduce poverty in the long term. We do not know how to build a thriving economy through aid from groups like the International Monetary Fund, from governments, and from non-governmental organizations.
Ending poverty is something that would require the creation of thriving economies in every country. We do not know how to accomplish this. Therefore, it is probably somewhat misleading to say we are not doing enough to end global poverty.
