Can somebody explain "Black Friday" in scientifically satisfying ways (read: leave your party book out of it)? What is this seemingly dramatic drop in prices that is adjusted so to endanger public safety rather than to ensure a more "rational" adjustment over longer times that perhaps "naive capitalistic" models predict to be more lucrative for all (consumer, seller, society that ensures the marketplace)?
Is this all plainly exploitation and procreation of an irrational mass of consumers that otherwise may not buy what they would realize not to need or is there something more subtle that could be justification for exporting such culture to as yet not infected human populations?
Is the core of it similar to apple/nike release dates, but without the brand specific aspects and other key differences, i.e. the irrational customer that needs to be manipulated to buy in impulsive ways?
