I still find it hard to wrap my head over the fact that most economist analyst is aware that continuous printing of money is deterrent to the economy and quality of life in the long-run, but still, the government keeps issuing endless bills. It's not my desire to politicize my views but ideally, economists should run most of the economic policies but it seems the economist is only a remote control tool used by the government to achieve political interest.
It seems the world now runs policies for immediate gains while trashing policies that bring future gains. Maybe I am having a distorted view, but looking at most government policies around the world, even a non-economist can tell that this will be disastrous in the future.
Economists give advise,but the politicians are making the decisions.Most of their decisions are only about gaining support in the society and wining the elections.That's why the political system of democracy is stimulating short term decisions(or policies for immediate gains,like you wrote).The people want less taxes and more government spending,so the politicians give the people what they want,in order to be reelected.This means higher budget deficits and money printing by the central banks.The economists know that this is dangerous for the global financial system,but they don't have the power and authority to influence the politicians and change their minds.
