Adding liquidity (aka printing money) just kicks the can down the road. Supposedly the US GDP last year was up close to 4%, but they failed to account for the 6% increase in the money supply, which means an actual 2% contraction instead which is a huge difference. In the US at least this has been ongoing since 2009. In the long run it causes more losses to the people overall while creating/propping up the upper echelons of a monetary cast system. An analogy could be getting hit on the hand with a hammer. It might be scarier to get a single hard blow but repeated medium energy blows are overall going to cause a lot more damage.
