Op well that is you point of view but the high cost of living and increase in the food prices and other commodities are very far from what you are saying. Let me start from the taxation. Nigeria is a country of tax free citizens and that means the citizens are not paying tax directly but they are paying tax like any other country in the world. Now how the Nigerian government tax the citizens. They tax heavily the manufacturing Companies so the manufacturing Companies in return increase the price of food and other commodities so the citizens pay the tax indirectly. Some people are saying that it is because of the importation of goods and the rise of the dollar.
But as for me all those ones are just Secondary to me and the indirect tax is the cause of the cost of living in the country.
You have pointed out a very good point, citizens of my country also do not pay taxes directly, even small shops do not pay taxes and the government has difficulty collecting taxes directly from the people. But the government does not ignore it and they impose high taxes on companies, that way they collect taxes indirectly from the people.
This is totally different from us, our goods and services are being taxed at 12% called VAT (Value Added Tax), this is one good way to generate taxes from the masses but reflects badly on the poor. The government should start working with the taxes again, revise some tax laws because we're basically using it for a century and the world hasn't been similar for the past 100 years. I think this is also why crypto has been a thing now to the riches, they can easily dodge taxes which is comparably high to the transaction fee on blockchain. If the government impose high taxes on rich people and low taxes to poor people, this will be a new problem for the society making it unfair.
But if there is a monopoly in Nigeria's food industry, that also causes prices to skyrocket. In my country, electricity is a monopoly business model and when they increase electricity prices we have almost no choice but to accept. Monopoly with government support is misery for the people.
I know little about Nigeria, but I do know that they have a high inflation rate. Same with my country, people are having a hard life with less jobs and opportunities.
