From the High Level Panel:
"It is tempting to apply universal targets at a high level everywhere, but for some countries that risks becoming utopian. The Panel would like every child not to suffer from stunting or anaemia, but that can probably not be achieved in all countries by 2030. We would like everyone to be covered by social protection systems, but not if that means reducing the quality of such systems to a meaningless level. We would like everyone to have a decent job, but that too is probably unachievable in a mere 15 years, even in the most developed countries."
