Answer:
Frugality can be defined as being completely careful in managing and using your money. Many of the social problems that exist in Untied States can be tracked down to the lack of money that people can use to increase their well being.
For example.
Every parents want to make their children have a proper education. This is no exception for parents in poor households. But, the cost of tuition for good schools felt a lot bigger for poor parents compared to richer parents.
One thing that poor parents can do under this situation is by being extremely frugal. They can cut down any form of unnecessary spending from their life. No designer bags, cooking all meals by their own, no new clothing's, etc. They can put all of that money into their children's education as an investment for their future.
