e.g. how do you sell 100 million smartphones when the population is only 50 million, and can hardly afford to buy 1 (and certainly not more than 1)? this leads to layoffs how do phone shops like verizon or t-mobile stay open if people aren't buying? same for phone repair places? more layoffs more laid off people means less people going out to dinner, ordering pizza, taking trips, buying new cars. those businesses clo…
