At one point in the past I was most definitely dealing with poverty and I found it a lot more difficult to get development tasks done at work. The reduced mental capacity is really noticeable but importantly it's also temporary.

Since then I've kept an eye out for disadvantaged people who do good development work. If they are able to produce things despite having a reduced capacity it's such a good sign that they have real talent. Poverty can be dealt with more easily than a lack of talent.

There's a great book called "scarcity" by by Sendhil Mullainathan and Eldar Shafir, that explains the mechanisms behind this, would highly recommend reading it.
