"Now listen, you rich people, weep and wail because of the misery that is coming on you. Your wealth has rotted, and moths have eaten your clothes. Your gold and silver are corroded. Their corrosion will testify against you and eat your flesh like fire. You have hoarded wealth in the last days. Look! The wages you failed to pay the workers who mowed your fields are crying out against you. The cries of the harvesters have reached the ears of the Lord Almighty. You have lived on earth in luxury and self-indulgence. You have fattened yourselves in the day of slaughter. You have condemned and murdered the innocent one, who was not opposing you."

The problem is- Jesus didn't chase the people behind the money changers out of the temple with a whip, it was the low-level workers he attacked. While talking about, as you quote, how luxurious their lives were.
Jesus was doing the Batman thing- beating up on low-level criminals while leaving the real people in charge behind the scenes around.
