Conservative estimates place the number of addicted gamblers at between four and five million, about half the number of alcoholics. The results of addiction are job loss, spousal abuse, child abuse, and debt. Over half of all those who seek help for gambling addiction have committed crimes to support their addiction. The most common forms of crime are embezzlement, tax fraud, theft, loan fraud, assault and robbery. Gambling expansion is always touted as providing new jobs and tax revenues.
Common estimates are that the social costs to a state are double the tax revenues.
So, expanded gambling is a bad bargain economically, damages families, and is incredibly poor stewardship of the resources God has given us. We need to be concerned.
