Why do many (but B”H not all) people who give Tzedaka insist on public recognition (i.e. name the building after them, get a plaque on the wall saying they donated, an award ceremony, etc.)?
Tzedaka, like any mitzvah, should be l’shmo, and hidden.
Because not everyone is up to your level of selflessness and humility. In an ideal world, it should be as you say. Alas, this is not an ideal world.
Better that people give for recognition than not give at all.
