The more money the banks print, the richer they get, with the side-effect that prices rise (they make the monetary units less scarce and worth less).
2-3% just happens to be the most they can get away with in the long term without the population getting concerned.
What the general population don't realise is that the value of goods and services are going down over time, due to efficiency increases, at a rate of around 5% / year. The banks can print enough money to soak that up unnoticed, and then an extra 2% just because they can. It's essentially a stealth transfer of wealth from the people to the banks and it's been going on for decades/centuries (before fiat, it used to take the form of coin shaving, impure metals etc).
You really see the effect when you look at house prices. They are roughly the same price in gold as they were in the 1970s. Rather than housing going up in value since then, it has been the monetary units going down in value, due to the supply roughly doubling every decade (look up M2 USD).
You can understand the incentive to print money when you realise that every year the banks are collecting interest on every dollar/euro/pound etc. in existence. And the banks don't really own any of them - they printed them out of thin air as loans and have to destroy them when the loans are repaid, but total debt only increases every year...
