The document explains fiscal deficit. It states that the government spends money on revenue expenses like salaries and capital expenses like constructing hospitals. However, the government's total expenses are always more than its total income from taxes and other sources, resulting in a fiscal deficit. This deficit is financed through government borrowings from the market or printing additional currency, with borrowing being the better option to avoid inflation. However, borrowing also cannot continue indefinitely and the only sustainable way to control the deficit is by spending less and earning more revenue.
