What is 1 "pro" and 1 "con" for operating in budget deficit?

Pro - Innovation and technical advancements would likely increase due to the government subsidising companies and corporations (from the increased spending).

Con - The nation will likely face a debt which will lead to a feedback loop of having to borrow more money as they don't have enough money of their own to spend.
