A Luxury Goods Tax is a policy where luxury items (such as expensive sports cars, private yachts, etc.) are taxed.
This tax brings in money based on how many Wealthy people live in the nation. It's favored by Socialists for the positive impact it has on Equality but Capitalists and the Wealthy oppose the tax, especially since it hurts the High Earnings they receive. It can also be a cause for Brain Drain.
