Spending money causes stores to make money. Their employees make money, and can then spend it to fuel the economy. The stores can buy more product from manufacturers, who can then pay their employees, who can then spend money. If you save your money, none of those people make any money, and less action goes on in the economy.

If you save money in a bank and do not borrow, the banks hardly make any money. If the banks make less money, they have less to lend to other people, who can then not buy anything, and the whole spending cycle dies off.

If people Save all their money and not spend it, it is bad; very, very bad.
