In 1994 the State of Delaware made a successful bet on legalized gambling. Legislation authorized three horse racing tracks (now racinos) to build casinos for slot machines, which the State designated as video lottery terminals due to constitutional restrictions. Operations began in 1995 and revenues from slots and numbers lotteries are now the states fourth largest source of revenue. Gambling revenue to the state represents a voluntary payment of taxes. Unlike income and business taxes that entail significant penalties for non-payment, gambling and excise taxes are voluntary payments. No one is required to drink alcohol, smoke, drive or gamble. If a person chooses to enjoy any of these activities, the price paid includes a tax. Politicians love voluntary tax payments.
