So when gambling has failed to produce enough revenue, maybe, as a fallback, they might consider raising taxes to, you know, pay for all the things they need.
Illinois’ debt problem is far beyond fixing by raising taxes. They promised billions on corrupt pension schemes that literally could not have been payed for except by passing the bucket down the line to the next ngenwration of workers. The dilemma is that you can’t get out of it except by filing bankruptcy, which aside from the question of whether it is even possible, would completely destroy an otherwise healthy state and local economy.
