When I talk to people about earning to give, it's common to hear worries about "backsliding". Yes, you say you're going to go make a lot of money and donate it, but once you're surrounded by rich coworkers spending heavily on cars, clothes, and nights out, will you follow through? Working at a greedy company in a selfishness-promoting culture you could easily become corrupted and lose initial values and motivation.
First off, this is a totally reasonable concern. People do change, and we are pulled towards thinking like the people around us. I see two main ways of working against this:
- Be public with your giving. Make visible commitments and then list your donations. This means that you can't slowly slip away from giving; either you publish updates saying you're not going to do what you said you would, or you just stop updating and your pages become stale. By making a public promise you've given friends permission to notice that you've stopped and ask "what changed?"
- Don't just surround yourself with coworkers. Keep in touch with friends and family. Spend some time with other people in the effective altruism movement. You could throw yourself entirely into your work, maximizing income while sending occasional substantial checks to GiveWell's top picks, but without some ongoing engagement with the community and the research this doesn't seem likely to last.
One implication of the "won't you drift away" objection, however, is often that if instead of going into earning to give you become an activist then you'll remain true to your values. I'm not so sure about this: many people who are really into activism and radical change in their 20s have become much less ambitious and idealistic by their 30s. You can call it "burning out" or "selling out" but decreasing idealism with age is very common. This doesn't mean people earning to give don't have to worry about losing their motivation—in fact it points the opposite way—but this isn't a danger unique to the "go work at something lucrative" approach. Trying honestly to do the most good possible is far from the default in our society, and wherever you are there's going to be pressure to do the easy thing, the normal thing, and stop putting so much effort into altruism.
The reason to make lots of money to give it away is elaborated on here, in the paragraph about the lawyer who wants to clean up the beach.
Summary version: More charities are funding-limited than volunteer-limited, and if you are making a sufficient amount of money, working one extra hour and donating the proceeds from that hour gets more done, saves more people, than using that hour to volunteer. The important part is to actually save people.
Saving people is far more important than giving consistently (If the best way to save people is to give each month, I want to give each month, if the best way to save people is to donate large chunks infrequently, I want to donate large chunks infrequently), saving people is far more important than having a good attitude towards giving (If having a good attitude towards giving makes me donate more, I want to have a good attitude towards giving, if having a selfish attitude towards giving makes me donate more, I want to have a selfish attitude), and saving people is far more important than spiritually developing in the process (I trust you can complete the pattern). I'm not saying these things are bad, it's just that they are subgoals of the thing you are trying to accomplish, which is doing the most good. Making a great deal to give it away, and making sure you don't backslide into selfishness are things to do to ensure that the most people can be saved. Regular giving is secondary in importance.
The goal is not fitting conventional patterns of giving, the goal is to help as many people as possible. To try to get a high score in the LIVES IMPROVED statistics column of the game of life. If something helps in this quest, do it, if it doesn't help, stop doing it.
