That's right everything always boils down to our present socio-economic debt based fiat money system! Maybe this is also why civilization never last, we all end up shooting ourselves in the foot, so to speak!!!
When I hear that it is not "economic" to do this or that, it always makes it very clear to me that human beings are slaves of their own socio-economic systems! How can we keep on making advancements when we think that it is not "economic" to try to explore new energy sources!!!
Eventually, it will end-up costing more and more to continue to use the same old, same old energy source, but then it could also become too late when it really is economic "feasible" to explore these new energy sources...
I guess this is how it really goes...
