Rich people in fiction come in many shapes. Wealthy Philanthropists are filthy rich, but they are very well aware of their privilege and they know they have been extremely lucky in life. In addition, they are not ignorant of other people whose lot in life is considerably worse. To balance social injustices, they try to use their money to help the poor and other people who are in need. They can help local people with whom they might (almost) interact, or they may be involved in various charity projects, or they may even start huge foundations or charity organizations. Some of the actions might be done anonymously. Why do they do it? Good Feels Good.
Being a philanthropist who does much good serves as a characterization device to show that the character has a heart, and to further develop the character as a decent human being and worthy member of the society. It might be apparent right from the start of the story, or it could be revealed as their Hidden Heart of Gold.
This character trope can also be to show that the donor is only doing it for power or fame. It can result in Screw the Rules, I Have Money!, where they threaten to stop donating if they do not get their way. This can also be used by villain characters to become a Villain with Good Publicity
A Wealthy Philanthropist is likely to be Non-Idle Rich and related to Royals Who Actually Do Something. They are equally likely to be a Self-Made Man or come from Old Money. When one of these is a member of The Team, they're The Team Benefactor.

- In the Batman franchise, Bruce Wayne spends large amounts of money on public projects. Not that it ever reduces crime in Gotham, but it's the thought that counts. His alter ego, on the other hand, reduces crime by punching it in the face. Not all Bruce's philanthropic projects are meant to stop crime, though. He feeds the hungry, takes care of orphans, contributes to hospitals and the like. So Gotham benefits a great deal from his largesse.

- Jane Eyre: Zigzagged with Lowood school for orphaned girls and its sponsors. Part of the building was built by Naomi Blocklehurst, late mother of its current "benefactor", the Rev. Mr. Brocklehurst, a pastor who thinks himself pious and generous, but who has a sick, twisted mind. The pupils all suffer from hunger and cold and lack of other supplies, and later lots of them die of typhus because they're weakened from malnutrition and dampness of the building. After that, the situation was improved by some wealthy people and the institution became useful and the orphans were indeed helped and educated there.
"When the typhus fever had fulfilled its mission of devastation at Lowood, it gradually disappeared from thence; but not till its virulence and the number of its victims had drawn public attention on the school. Inquiry was made into the origin of the scourge, and by degrees various facts came out which excited public indignation in a high degree. The unhealthy nature of the site; the quantity and quality of the children’s food; the brackish, fetid water used in its preparation; the pupils' wretched clothing and accommodations—all these things were discovered, and the discovery produced a result mortifying to Mr. Brocklehurst, but beneficial to the institution.
Several wealthy and benevolent individuals in the county subscribed largely for the erection of a more convenient building in a better situation; new regulations were made; improvements in diet and clothing introduced; the funds of the school were intrusted to the management of a committee. Mr. Brocklehurst, who, from his wealth and family connections, could not be overlooked, still retained the post of treasurer; but he was aided in the discharge of his duties by gentlemen of rather more enlarged and sympathising minds: his office of inspector, too, was shared by those who knew how to combine reason with strictness, comfort with economy, compassion with uprightness. The school, thus improved, became in time a truly useful and noble institution."

When he read a premature obituary for himself in 1888 that painted him as a "merchant of death" , he became concerned about what kind of legacy he was leaving the world.
