Many people choose to go into the ministry, for instance, because they are answering a call that they consider more important than money. Some wealthy people give away much of the money they have earned because they want to do something they consider more valuable than money. Bill Gates is a recent example, and Warren Buffet is another.
I think the easiest example of this (especially around the Holidays) is gift giving. We say it is the thought that matters and for most people that is true. I would much rather have a personal, thoughtful gift or even a homemade gift rather than money. Money tends to be very impersonal. Of course, it all really depends on the person. Some people would rather have the money.
A personal example from my own family would be between my father and my grandmother. As my grandparents were leaving our house one day, my father plucked a flower from bed in the yard and gave it to his mother. She cried. I think the sentiment and gesture meant more to her than if he had bought her a dozen roses. It isn't the amount a person spends but the thought behind it.
For some individuals, money probably does trump sentiment or emotion. For others, it probably does not. I do think that money has tended to erode some personal relationships, for instance with locally owned small businesses, but I would find it difficult to generalize about something like this across our society. As the previous post says, it is probably best to focus on your experiences, and the relationship between money and sentiment in your own life.
The kind of incidents that show this most clearly are personal ones, not ones that are famous. You should try to look for incidents in your own life or the lives of those around you that show this.
As far as famous incidents go, there are a number of examples of athletes choosing to get less money in hopes of winning championships. The case of LeBron James in 2010 was like this. He could have had more money, but instead he chose to go to a team where he thought he'd be likely to win a championship, which is an emotional/sentimental choice.
many couples who married for money didnot last long...money cant buy true love,deep emotions and true feelings...with the money we can make the people interested with us but the real love comes from mutual respect,caring, and sharing experiences... so money can never replace emotions.
