"The conversion rate is not true" ... reminds me of when my dad traveled to Angola in the 1980s and there were currency controls in place. Government workers there would be paid in the local kwanza currency which at the official conversion rate would seem to be reasonable dollar-wise given local black market dollar prices for goods. However, nobody wanted kwanza at the official government rate, and instead a dozen eggs might cost a month's government worker salary at the real, unofficial conversion rate. To make ends meet a government worker would need to leverage their access to rare goods. To maintain the fiction of the official rate the government would offer a limited supply of rare goods (eg pharmaceuticals) to government workers in special commissaries. Workers would buy these supplies at the official government store kwanza rate and then sell them for dollars on the black market for their true local demand black market value. Then they could buy eggs for fewer hours of work. It was a very precarious, risky, and time consuming operation for these workers. Incidentally in 2017 Luanda, Angola, was the most expensive city in the world with a 2-bedroom flat renting for US$6800 monthly. Still inefficient.
