I think most of it is just oiling the wheels of the political and buisness elite as backhanders/bribes call it whatever but the huge amount that we spend should be A, agreed by tax payers and B, every penny accountable for. I do believe some aid is necessary but id say 90% dont get anywhere near the people who need it as its just used to buy influence and sweeten government contracts back for our politicians own and freinds/family businesses just corruption really
