The moneychangers in the Temple didn't represent "consumer culture," a luxury of modern capitalism. They were more likely symbolic of the Temple elites' collaboration with the Roman occupiers and the exploitation of the devout.

The disruption of the Temple was probably intended to hasten the arrival of the kingdom of God, when the human condition would be transcended and justice would prevail. Of course it set into motion the series of events that would result in Jesus's horrific execution.

The gospels don't portray Jesus as polite about this mission. He was extremely critical of hypocrisy and corruption. So should we be.
