It's supposed to be a meso sink to keep the amount of currency flowing in check, but 3% isn't going to go far.

It goes to paying off the deficit.

Every time the Black Wings Party gets voted into power they spend like drunken sailors and then when they're on the outs again they complain bitterly about "the deficit" and how we have to cut back spending on non-essentials like education and healthcare.

The Resistance Party keeps trying to raise revenue by increasing taxes on the top 1% of MapleStory players, but the Black Wings Party always managed to vote them down in favor of "big oil".

It's either that, or it's a way of removing mesos from the Maple economy to try to balance the illicitly gained game currency from the bad kids doing their things.

Duey loads the sacks of mesos onto his big red truck and drives them off, never to be seen again.

The monsters take the taxes.
No wonder they're always dropping mesos when eliminated.

it just disappears
they want to have less mesos around which makes mesos more expensive and which in turn makes items more expensive and ultimately make people buy those cards and spend nx at 'trade'
