I don't claim it to be a fact, I claimed that it is silly to be sure that it's certainly only supply and demand, in the 'easy supply and high demand' sense. I claim we do not know if that is a fact, and it is actually quite possible that the supply side is more problematic compared to what some may think.
In fact the whole world has a supply problem nowadays. It is sourced to energy prices. Everything is harder to produce. For those knowing basic physics it is easy to understand: Energy = Work => Products and when Energy is cheap it comes to reason that production is cheaper. Now, if you combine it with basic Economics that Work = Wealth, then you know what high energy prices / scarce energy means to the world and why we had or have a global economic crisis.
