A sovereign government's budget is not like the budget of a household or firm. Governments issue the currency, whereas households and firms use the currency. As the chartalist, or modern money approach, explains, modern governments actually spend by crediting bank accounts. It really just amounts to a keystroke, pushing a key on a computer that generates an entry on someone's balance sheet. Government can never run out of these keystrokes.
