When Asia minor became a Roman province how did it benefit Rome?

Asia minor became a province bit by bit but probably the most significant transfer of power in the region happened when king Attalus III of Pergamum died and left his kingdom to the Romans in his will.

This happened in 133 BC at a very interesting time in rome and the money from pergamum went to an unusual use. there was a class struggle of sorts going on at the time where a tribune called Tiberius Gracchus was trying to fairly redistribut public lands to people and the rich senators were blocking his attempt. the money from the lands in Pergamum allowed Tiberius to carryout the land reform without funds from the senate and increased Tiberius' popularity enormously.

In the end though, the senators fearing his popularity and perhaps forshadowing Julius Caesar years later, clubbed Tiberius to death in the forum. He is often looked back as the first communist and was revered by Karl Marx
