80,000 hours is all about making a difference in an effective way and one of the most effective things you can do is donate to a cost effective charity. There has been some talk of matching donations and how it might not always increase how much money is ultimately donated. But there is a type of matching that can be very powerful.
Some companies offer large matching contributions and sometimes offer more than a dollar per every dollar donated. Some companies also offer grant money for volunteer hours or matching donations for participating in walks/runs/events for charity, and also match gifts made by retirees and/or spouses. If you’re pursuing an Earning to Give career, then a good matching scheme could be even more important than what industry you enter. In many cases it’s probably easier to find an employer who matches than to earn a much bigger salary.
