The problem is caused by inflation, the cost of gas and petroleum product has affected the high price of other commodities. In my country, one need to spend high to have a good meal and it has been a treat to the poor who cannot afford two square meal. The rate of population is increasing, the rate of corruption is increasing and still there is an ongoing way. I wonder how the price of things will be like in the next 10yrs from now because presently, there is nothing showing that the price of food will be stagnant.
Even if there was no Covid, no war and no energy crisis, inflation would still increase over time, because there are many causes of inflation as mentioned by Z_MBFM. According to my understanding, inflation is an inevitable part of the world economy and it will increase and cause an economic crisis at some point. I mean the crisis will return soon in the future. So, our job is to prepare them for bad things in the future and bitcoin can be one of the effective solutions to deal with inflation.
