The best thing to do would be to learn how the lottery business works. Im not saying that he should change his morals but practiaclly speaking, he needs money. He should also study why there is no lottery on their place yet and verify it. To go with the offer would be the best option but if he has something in mind like other business where he doesnt have to “sacrifice” morals. He can consider it too.
Lottery business most of the time becomes a lucrative business, so if he wants a good passive income, he can accept this type of business. Because no matter what, these gamblers will find a place to put their bets. Remember, there are so many online businesses now. So why not just grab the opportunity while it is still profitable?
