Question type: poll
If you're a pure altruist, this question doesn't apply to you.
Number higher than 100% are possible if you'd borrow money, although it can become weird in scenarios where you stop being economically valuable and/or money becomes obsolete.
This question assumes you have an "egoist budget" separate from an "altruist budget" which might not be the case. If it's not the case, you can answer a similar question that works for you, such as "the fraction of your total budget".
