Well let's consider the imported goods in Iran, like phones, laptops, most basic ingredients for home furniture, and other goods.

An average family of 3, needs savings, laptop or at least a phone (due to covid and the aftermath of the revolution, many classes are still held online) for studying, paying bills, paying loan bills (because no one can support their family with the wages alone), and many more necessary expenses leaves many families in debt.

The poverty line in Iran is almost 4,5 times the average salary. And I do mean average not minimum wage.
