in a lot of todays workforce, and to many people as well, time IS money. any jobs where you are paid by the hour are just this. your wage is according to how important your time is spent working at that site, nothing more. your output at that company or job is almost arbitrary to the amount of time you actually spend working for them. incentives to work harder and improve preformance amongst people with shitty jobs are completely lost due to this "time is money" notion. however with the job market in its current conditions, these "unwanted" jobs are actually in high demand which changes these incentives to simply not getting fired.
Another fascinated thing is the material and convinence aspects of it, which strictly pretain to the ones who have enough of it to use in situations where money can help you. things like valet parking are a good example of this. why park your own car for free down the street when you can pay someone to do it for you and you save all of a few minutes. money becomes a large role in peoples live in which it does govern our own time and wheter were willing to spend money to spend less time on something or vise versa which when you break it down, is very unusuall.
