Too many products and services, too few pockets willing to buy them, therefore more and more ads to capture people attention and convince them to spend on this or that. Problem is: attention time is finite but products and their ads are not; every minute of ads for product X takes away people's attention from product Y in the same time frame, so it's just a matter of time before product Y makers decide to fight that with -you guessed it- more ads, then product X and others will do the same - rinse, repeat. We better find a new system or we're fucked, as the one we have now literally tries to cure itself using the same poison it's dying from. I have no ideas on how to solve that problem, aside noticing that the trend is potentially catastrophic.
