Do "gambling writers", the Wizard of Odds/Vegas, for one, the gamblers much more harm than good?
On the one hand are the disreputable, so-called "mathematicians" who "shill out" meaningless and impractical long-run player-advantages; and on the other, the "system" scammers who, availing themselves of some the formers' own words, declare, "The math can not be overcome, (so there must be a few simple, get-rich-quick "systems" to do the job instead.)
It's my belief that mathematics, coupled with the prudish obsessions of such "regulators" to fairly apply it universally to all casinos, has inadvertently become the 21st century's basic political justification for casinos. Because also no matter how "well-oiled" the means, sometimes the ends, whichever, are just not appropriate and constructive.
