I also don't get it. What is the point of boycotting the supermarkets?
The idea is to get the point across that they cant charge markups of over 50 to 100 %. Of course this wont work, but at least it shows that some civil discontent is taking shape. Now we will have to see who it gets aimed at...
Although it is easily discernible that inflation is caused by an increase in the money supply and years of misguided policies, it is also important to note that many retailers get away with charging ridiculous profit margins here. In the US, in the grocery business, you are very lucky to make 5 - 10% markup. Here the norm is to markup at least 50 %, and many cases the double. This to me is one of the main problems with the Argentina economy - retailers and business people are always focused on buying for X and selling for 2X. Now I know that this is not always the case, and I am sure David Glen will have some input on Profit Margins (see his detailed post on the cost of doing business in retail here), it more often than not is.
I would bet that markups at Carrefour & Coto among other big name grocers is above 50% - so this is the point of the consumption blackout.
-- I am editing this post since I erred in my original post writing profit margin when I meant markup. Apologize for the confusion & lack of clarity, at work and not very focused!
