So, apparently there can be a snowball effect here...

Whether you're a New Jersey mall rat or a farmer in India, being poor can sap your smarts. In fact, the mental energy required to make do with scarce resources taxes the brain so much that it can perpetuate the cycle of poverty, new research shows.
The findings, published in Friday's edition of the journal Science, indicate that an urgent need — making rent, getting money for food — tugs at the attention so much that it can reduce the brainpower of anyone who experiences it, regardless of innate intelligence or personality. As a result, many social welfare programs set up to help the poor could backfire by adding more complexity to their lives.
"I think it's a game changer," said Kathleen Vohs, a behavioral scientist at the University of Minnesota's Carlson School of Management, who wasn't involved with the study.
There's a widespread tendency to assume that poor people don't have money because they are lazy, unmotivated or just not that sharp, said study coauthor Sendhil Mullainathan, a behavioral economist at Harvard University.
"That's a broad narrative that's pretty common," Mullainathan said. "Our intuition was quite different: It's not that poor people are any different than rich people, but that being poor in itself has an effect."
