If we have so much debt here, it is because our democracy is turning bad. Politicians are used to promising lots of demagogic and irrealistic social programs so as to be elected, and I think that 's why debt is mostlyan "Occidental" problem.
Moreover, here, nobody was asking governments "where do you find that money", because people were happy to receive money from the government and to have a large welfare ! You know, in one of our History schoolbooks, I remember there was a map of the world, showing endebted countries, like the map posted on the top of the page. Nonetheless, Western countries (USA, UK, France...) weren't coloured, they were let in grey, like for instance Somalia in your map. So, in class, we spoke about the Indian debt problem, the Brasil debt problem, but in fact, the debt issue was our. And we are realizing it only now !
I hope it is not too late...
Sorry for my bad English, I'm French !
