There is a public clamor to do that, and it’s on local news almost daily because of some criminal cases attributed to gambling. I have a neighbor whose daily allocation is the equivalent of $2 now; it used to be $1, His reason is that he only has a few bets to get his wins, so he needs to add more to his bankroll, and his daily take is $15 so its a matter of weeks before that $2 becomes $5 and he will have less in his take home.
These are the people that lawmakers want to protect. Still, I disagree that they need to increase the threshold because these gamblers will likely resort to unlicensed or underground casinos that offer a lower deposit threshold.
