I thought the question of the subject can easily be googled/explained. The hard question is why are wages not keeping up? Greed? But greed has always been there. Shouldn't people stop affording certain things and that lead to a price drop? I hope an economist answers this but my theory is that most businesses have consilidated/merged into larger businesses over that past two decades and this means they can get by for a couple of years with losing revenue so long as when customers come back the price that is acceptable to charge would make up the difference of whatever they lost
