This is hilarious, although some people actually believe that poverty is a mindset issue so I hope to god you're joking
Say, spending 3 hours to save $10 is usually a bad deal, that time can be invested much better. But if one keeps doing that, they end up in a situation where spending 3 hours for $10 is what they have to do, because they don't have a spare $10, and there are pressing needs.
It's a trap. But it ensnares you through a mindset, not through a want of $10 initially.
To add to this: if one keeps doing that, or they're unlucky: Being born into the wrong family, or socioeconomic class. Being the victim of a crime. Having your transportation stolen or break down. Etc.
There is a mindset to some degree with feelings of poverty. Though, yes, real poverty is a reality.
