People talk about tech giants, but Facebook and Google are actually advertising giants. They pour much more money into their advertising than they do into r&d.
Many brands have a cost structure where, for each product sold, more money goes to advertising than to the person who actually made the product. Sometimes 2 or 3 times more. That’s where the battle for attention is taking us, a place where attention from customers is worth much more than the effort of the worker.
None of this is inevitable, advertising should be heavily taxed and regulated.
Nations that trade extensively with each other don’t go to war. Trade wars are an accelerator of armed conflict.
