In general, the ComiCon states is the state in the socialist East they profited, of course funds, rather cheap energy from the Soviet Union. And they still profited after the oil crisis in 73, when many developing countries of the South has got real problems, and we have to keep those in mind. So not so West was hit by the oil crisis in 73 and 79. Peace states in Africa who just tried to build up industry, they were the real victims of the increasing crisis because they were not able to pay energy anymore. And the debt crisis in many parts of the world, and especially the poor countries, what's coming up then. So let's get back to the socialist yeast. After 73, the prices were rising a little bit in the socialist countries, but not that much. So they profited, because they got the five year planning and the prices were going up a bit later. But after 79, when the prices were getting up, once again, and the Soviet Union decided to sell more gas, and especially gas or oil, but gas to the West. This led to shortages in the oil delivery and gas delivery in socialist countries. And this was a real problem, because now they realize that they are depending on the Soviet Union on the power and the energies power of the Soviet Union. And they had to look for alternatives. And it's quite striking that some countries who had their own energy like Poland was cold, could stay a bit more independent, which has consequences, all the independent movements and so on. Also, Romania was a country with some kind of energy resources. But other countries like East Germany really got into problems, because they were, they had petroleum and chemical industries selling the cheap oil transformed to petrol to the west. And this business was, in some way breaking down. And so the industry and the GRS suffered. And what they had to do was to get back to brown coal. And actually a brown coal was something which they had not in mind to produce that much in the future. But now in the 1980s, they had and this had big consequences to also for the environment. And also for the whole atmosphere that was coming. There was a kind of environmental movement that was criticism about the brown coal, and countries like Poland countries like the GE or had huge steps to do to this specific constellation in the 1980s. And if I made last point, yes, please Oh, is because in the mid 1980s, the oil prices are going down again, the West is really happy. And this is really important for the whole economy, let's think of politicians like him would call the Christian Democrat on record setter, the conservative in Britain. That's why they succeeded in the late 1980s. Because we were so lucky that the oil prices were going down, inflation was going down. And so they were could win elections and so on, ya know, and author Ron rain, so they're on the right side. But in the socialist countries, the prices were not going down as quickly as in the West, which was market driven surprises change quite quickly, but they have the prices of the planned economy. And so they say, had to pay higher prices for longer time. So things even got worse due to the
