It would be pretty difficult to argue for less aid, given the imbalances in wealth, between rich nations and poor nations which have got worse over the years if anything.
I think the issue isn't that it is different aid as such, i.e. there is already aid for development as well as aid for emergencies etc, but the issue is the politics involved, and has been historically. (which is no different to domestic matters in fact, too much money is wasted and political agendas get in the way of what is common sense)
International Politics (and self interest) is determining how the money is spent, and this can never be good. Indeed forcing rich nation's own capitalist structures and ideals etc is certainly not the answer. Even the transnational NGOs that disperse Aid have their own agenda and spend their time being accountable to the donors of aid (which is understandable) but this doesn't mean their actions are always the right ones for the receipients of aid.
Bottom line, rich countries, who control the organisations that have the most power, need to back off, they do need to contribute more, but they need to work with local governments better and allow countries to develop their own way out of poverty instead of practically dictating what gets done.
So, it's not a different form of Aid that is needed, it is a different form of governance.
