Donating now vs. saving up for a high passive income

Is there any sort of consensus on whether it is generally better to (a) directly donate excess money you earn or (b) save money and invest it until you have a high enough passive income to be financially independent? And does the question break down to: Is the long term expected return for donated money (e.g. in terms of QALYs) higher than for invested money (donated at a later point)? If it is higher for invested money there is a general problem of when to start donating, because in theory, the longer you wait, the higher the impact of that donated money. If the expected return for invested money is higher atm, I expect there will however come a point in time where this will no longer be the case.

If the expected return is higher for immediately donated money, are there additional benefits of having a high passive income that can justify actively saving money? E.g. not needing to worry about job security too much...
