We are all Keynesians now

We are all Keynesians now means that almost everyone agrees with the economic ideas of John Keynes. John Keynes said that instead of trying to save money, like what people usually do, governments should spend more money to help their economy grow. This kind of spending is called stimulis, and it means the government is investing in things like roads, schools and other things that help the people and make the economy stronger. So by saying we are all Keynesians now, it means that a lot of people think that John Keynes was right, and that governments should spend money to help the economy.
