Poverty in Iran stands at 20% according to whom? you or payvand or aliens? LOL
Poverty in Iran (according to the UNHCR it means an average income of less than 1.5$ per day) stands at below 2% (in fact the interval 0% to 2%), just like all developed countries. With the distribution of cash to poor Iranian families, any Iranian who has registered for subsidy cashes is paid almost 1$ per day. That means if we even talk about the higher standard of poverty according to the UNHCR and we define poverty by an average income of less than 2.5$ per day, still less than 5% of Iranians will be below the line.
According to the UNHCR, Iran is an upper-middle income country with a PPP per capita of +13,000. That, by no definitions, means the situation of Iranians is bad and since the ratio of dollar to IRR has increased then you could expect that in new calculations Iran's Purchase Power Parity GDP increases. It depends though, because as you know the central bank of Iran has fixed the rate of dollar at ~12,000 Rials for the government budget, even though dollar is traded as high as 20,000 in the local market but still that will be the ratio used by the IMF, World Bank or other economic institutions.
So what I'm trying to get at is by no means you could indicate that poverty in Iran is like 20% now and in future the percentage of the poor will even decrease in statistics. Yes, you could build an arbitrary list and put anything you want in it and then by statistics come with a number that if an Iranian family has an average monthly income of less than 2,000$ then it's poor, but you shouldn't expect others to accept your numbers. As long as UN reports are concerned, Iranians are getting richer, better educated, the GINI coefficient is decreasing and life expectancy is getting higher. That shows a growth in Iran's human development index and that means the situation is good.
Pineapple is 15$? You must be kidding. You mean pineapple is 30,000 Tomans? Really? Since when? I stopped reading the article just after that. Please do some research before talking about poverty.
