In my opinion the easiest part to share is money. Here, I'm not considering a particular section of people, misers, but other than them the people have no time for others and emotions it's far away from human beings.
Only thing which one can afford to share is money because sharing time means the personal space has to be shared. Sharing emotions means to be answerable to the person.
Thus, time is the easiest bet because nothing is attached to it.
