While it maybe be true that large pools of institutional money are better at buying political favors, influencing scientific research, and swaying foreign governments, it has always been known and is frequently demonstrated that individuals always do better at loving and caring for other individuals, tend to be wiser stewards of money, and view their giving and service toward others as a means of actually helping them, rather than a means to gain political power or popular prestige.
