Time is another of the great equalizers (death being another). Everyone has the same amount of time in a day, week, or year. We use our time to play, work, sleep, and various other activites. Some people turn their time into money through work. Some people make $5 an hour while others make thousands of dollars an hour. Some sleep 10 hours a day while others sleep 4. Some people look at time like money while others do not. Do you spend and invest time? People who do tend to get worried and upset if they do not feel they have gotten the return on their investment they were expecting. This return may come as a feeling such as happiness, satisfaction, or love. It may also come in monetary means. The more money a person has, the more valuable his time becomes. Therefore, a relatively poor person might invest 4 hours for $30 in return. An affluent individual might need $3,000 in exchange for those same 4 hours. Money is not the only factor here. A wealthy individual will accept -$ for time if the happiness, satisfaction, love, etc. is great enough. In conclusion, as a person's monitary wealth changes (a variable resource) it's value relative to a person's time (a static resource) changes.
