Gambling and speculation
We are faced at every hand with enticements to risk money in anticipation of disproportionate gain through gambling. Some governments employ gambling as a means of raising revenue, even presenting it as a civic virtue. The Religious Society of Friends continues to bear testimony against betting, gambling, lotteries, speculation, or any other endeavour to receive material gain without equivalent exchange, believing that we owe an honest return for what we receive.
