Actually the same reasoning applies to poverty disease control and eradication: You cannot control/eliminate/eradicate if you do not have a environment conductive to that: Try eliminate whatever-disease when there is a war going on. Or when people simply have other issues at hand like getting food for the day.

I totally agree with this. And yes it is poverty that definitely makes people ill but it is also "culture" or so called "way of life". It's bad enough what we are actually eating and drinking and with "fast food culture" it is just way worse...We already see statistics that next generation will live shorter than previous one...Add stress that they are living with each and every day and you don't need to ask why...
