I think is "Time"
Time in some way is bigger than the universe No matter how good we are, we may able to rule the universe but we can never rule the time. We can do a lot of things to change this universe but we just cant change the time.
Rich man wants more time to make even more money or more time for them to live and enjoy life
Poor man may just seat down all day doing nothing and thats why they are poor and always think that they have too much time to waste.
At last, if we eat up our time thats mean our time is due and we will be either heading up high or going down low.
Besides "time" i cant really think of any words for now that can explain those 4 points better. " I may fail but I've tried" saids Bill Clinton on Fox News interview.... hahaha
