I believe the root of the problem lies with the people. Everyone wants to make a profit and no one wants to lower prices back to where they were. This greed is allowed to thrive because the government either lacks the ability or the will to control it. They seem more concerned with their own wealth than the well-being of the people. Unfortunately, I don't see prices going back to normal anytime soon.
I don't think if there had been anytime we the citizens ever knew or said the hike of goods in your country is being pointed at the high rate of the USD instead it was the government who came on their own strategies whinnying and pointing hand on the high rate of the dollar being the caused of the high increase of good in the country and they're still the ones whom had fought earnestly to recover the value of the naira just as you've also said with the value of USD over naira today is a valid rate enough to quench the hike increase or goods but yet nothing seem to change in our markets til date.
Do we really have to say the value of the USD has never been a point towards what we're facing today's? This is questionable and only the government is answerable to that and not any of us as just citizens which they've always looked down on us as it's obvious that all they cares is the wellbeing of themselves and within their circles.
We don't need to be told if they cares about the common man's or not, it's practically obvious that they don't in as much we sees the riches getting richer and the poors are getting poorer without empathy of the government towards the uncalledfulness.
Does it even think the price of goods would even return back to a level we've been enjoying the economy system even when things still seems hard as at then?
Nothing seems impossible but Little bit looking at the nature of our governances of times after times the whole things seems impossible to attain a comfortable stage again in their country for a common man.
