Is wealth inequality so extreme that it’s OK to be a ruthless trader?

Wealth inequality globally is incredibly high. Perversely, this can be an argument in favour of working in finance.
Many people are concerned that ‘earning to give’ in the financial industry is overall harmful for the world, even if you give away most of your income to outstanding charities.
To figure out if this is true, we have been researching the size of the harms (and in some cases, benefits) caused by finance. (Though please note 80,000 Hours is not just about earning to give and in fact we think it’s the best path for only a small share of our readers.)
One of the concerns we’ve investigated is that some parts of quantitative finance are a socially-useless competition between traders that only changes who gets some amount of income, not that someone gets it. I think this is true, but the incredible amount of inequality in the world makes this argument against working in finance fairly weak.
If you make a random clever trade on a stock exchange and beat some other trader to a profit by 1 millisecond, whose pocket is this money coming from? A poor African farmer? No, they have no wealth to take. A middle class American family? It’s possible, but most of their wealth, if they have any, is probably in their house or bank account.
We don’t have perfect figures here, but looking at reasonable estimates,


When I was an undergraduate I came to fully understand the depth of the world’s problems: tens of billions of animals were suffering in factory farms, humanity faced the risk of catastrophic nuclear war, billions continue to live in horrendous poverty, and that was just the start. I wanted to solve these problems, but when I tried to take concrete steps I mostly felt powerless and frustrated.
