Thank you, and nicely put as well.
Beyond the points evoked in those "Tweets", you rightly touch upon the benefits Iran's popular masses derive from the ample subsidies on basic consumer goods, as well as from the unsystematic collection of taxes (a great many companies have special arrangements exempting their employees from paying the income tax). This comes into play when evaluating the living standards of the average Iranian, and most countries do not have such a subsidies system in place.
Now Sapir is focusing on the comparative weight and importance of a national economy (rather than on living standards, although the two aren't entirely unrelated of course).
In regards to this, he mentions the relevance of GDP PPP over nominal GDP indeed. But in addition, he goes on to introduce a second aspect generally left out of discussions: namely, the proportion of the service sector relative to the manufacturing sector in a country's economy.
And he stresses that nowadays, the service sector is overvalued - meaning that if you have two economies with identical GDP's, the one with the larger manufacturing sector will prevail in terms of its share of the world economy, even if the GDP figures won't show this fact.
Here Iran is presenting a particularly favorable picture, with a service sector no larger than 53% of overall GDP. This is even slightly less than Russia and China, and it puts Iran's true share of the world economy above countries with a similar GDP but larger service sectors. EU economies however, 70% of which are made of services rather than production of commodities, or the USA economy where this figure stands as high as 76,89% (2019), are weighing less on the global scale than what their GDP's - even their PPP GDP's would suggest.
I totally forgot to mention property taxes as well... People cry communism coming to Iran. but its not communism when the government literally "property taxes" you on land/house you own 100% outright.
There is even discussions now of a "equity tax". and you know its coming just like the carbon tax, and every other tax they float around. that means if you paid 300k for you house, and you sold it 10 years later for 500k. you owe the government a massive tax bill on that 200k difference.
They are even going into inheritance taxes. windfall taxes.
The "west" achieved it living standards on the back of centuries of colonialism (Looting) of poor countries. They still benefit from uneven trade/financial policies that are designed to favour western countries and their "hard currencies"
alot of dumb people take that and compare it to todays Iran. And blame the government for the fact that Iran was a banana republic pre1979. and a plaything for the strongest empire at the time (either Russian, British, or later on American). who had its resources looted....
Its also funny because the same brain dead people actually long for and are nostalgic for that slavery era. They want Iran to go back to being a plaything of the biggest powers. so they can watch naked westerners on tv dancing, and supposedly buy cheaper iphones (I have literaally heard that from some people ).
Since 1979 Iran has endured 8 years of imposed total war, followed by decades of sanctions increasing in intensity. There is not a single country on earth who could have weathered (let alone develop with) all these sanctions and economic warfare suffered by the west.
Untill the day comes that these western vultures take their slimey hands/eyes off of Iran, Iran will not be able to reach her full economic potential unfortunately. There is not a government on earth who could do better given the circumstances...
