Why Not Print More Money?

If the government can print money, why doesn't it just print money and hand it out? Economics Prof. Antony Davies explains that understanding why money was invented can explain why it is not useful for the government to print money to give away. Increasing the amount of money available for goods and services will only increase prices: this is inflation. If everyone has twice as much money but everything costs twice as much as before, are people better off? Having government print money will not increase wealth.
