As a Rule ... all Gambling is Scams ... Accordingly, the Lotteries are also Scams, though some could enjoy the local government/legal cover.
But all that aside, Lotteries are not the sensible way of changing ones fortune... Sincere, and Honest ... Hard Work ... Is.
Imagine millions upon millions of people "betting" their hard labors earned money to buy lottery or Pool tickets ... and a few; maybe ten or a hundred winning that accumulated money ...
But the Winning Number "happens" after 90% of the accumulated Jackpot money has been "siphoned off" by the Lottery's Sponsors and Protectors ... for reasons ranging from Philanthropic to Sports ... from local to Super Taxes.
Usually, only around 10% is given away as the Prize/s to one, or a few winners.
The Media then runs stories of changed Fortunes ... of the "average", people belonging to the lower and middle classes ...
The TV, Press and Scam Tabloids then show the winners planning a life of opulence... off the Prize money, for the rest of their days.
Because, Media, besides the Secular Governments and Con-men, is one of the Three Prime Sponsors and Beneficiaries of all Lotteries and other "legal" Gamblings.
