Suppressed Inflation happens intentionally or non intentionally
In recent years its been happening due to the fact of having Naive politicians, that as the saying goes did not see further than the tip of their noses. due to this reason or not their focus was directed out side their countries, and their people,s needs, mainly t words wars and the game of war.
Off course some time some politician would catch up with the trend and shift the ship a way from the drift but yet the spell of the suppressed inflation would still be there. an example of this is the situation with the US financial market now a days.
I would not be surprised to know that there is always this intention on the part of some aristocrats to set the ship backwards .
