Torah values encourage people to spend less on current expenses than what they earn. A person who uses self-control to successfully delay gratification and to save money is freed from the servitude of materialism. It uplifts us and brings us closer to eternal values. It allows us to tithe, to establish ourselves financially and even become wealthy, to use our money to expand our families and to help our children get an education and start their own families.
Additionally, individuals who waste their money become enslaved to their job. Their fear of being fired may force them to flatter, lie, and act against their conscience. Those who habitually save have more freedom to do as they please. If the employer demands they act in an unethical way, they can let themselves be fired and then calmly look for a more ethical workplace.
