This is the 1st time I've heard about a salary lottery and I'm curious to know in which region exactly this is popular? For me, such entertainment seems "wild" and I'm 100% sure no one here would want to participate in such types of bets.
This topic would be better suited for discussion in the gambling section.
No, this topic does not belong to the gambling board. It is better on the economic board and not related to gambling because this is neither gambling nor betting nor lottery. If you read the OP post, you will understand how it does not belong to gamble board, I guess you did not read the OP.
