I have never been sold on the idea of demonising politicians, yes Thatcher is hated by many and yet she took some really tough decisions to the long term benefit of this country, likewise Blair did the inconceivable and made labour electable, he deserves credit for that! I would prefer them both to the current line up.
Bill gates will only be taken seriously by those who admire his business acumen, there are huge problems with migration, it is not entirely the fault of this nation however we do need to coordinate our response including offering support beyond NGOs to resolve medical, political and humane problems in the countries most seriously affected. Most of these countries have populations out of control and suffer drought and famine, these are all things which could be addressed so why aren't we?
We pour millions into foreign aid why don't we
Target these countries and develop their economies and natural resources it's not rocket science!
