I think things that make retailers get greater profit because they can sell directly to the last consumer, this makes them able to raise higher prices than wholesalers, of course this is an effective market strategy for getting big profits.
They can inflate the price and just used the unfortunate incident like covid or any crisis happening in the world so that they can increase the price of the product which is necessary needed at that time. This is totally bad to the economy since this one really affect everyone since this will initiate for the price of other product to rise up to.
Government need to step up on this since they are the one who can control the price of each basic necessities and if they cannot stop those greedy businessman then maybe this will be one of the reason the inflation rate rise up.
In a country where the economics of the economy is not regulated, in a country where extortion is a normal act, in a country where agencies which are assigned to monitor trade and standardization does not work, either they are being soaked in corruption and bribery, that is the resultant effects.
The retailers always increase the price of products at their wish leveraging on the circumstances such as covid-19 and the recession that is gripping the whole world.
When the retailers suddenly increase the price of the product, the wholesalers will understand that they are making less again than the retailers they will tend to increase their own price. When this happens it will finally fall back to the final consumer who will have a double increments on the price of products they are getting. That is reason any product you get for $10 today, in few months time you will no longer be able to get that for $10.
Thank my goodness we have bitcoin were one BTC will be equal to 1 BTC and it is resistant to inflation. I pray that the Bitcoin technology dominates the world very soon so that everybody will enjoy the freedom which I think they deserve
