A casino can bring employment to a community, but the promise of increased employment might not materialize. For instance, a casino in an urban area might have a diverse labor pool that would ensure that locals are well-trained and experienced, but the same is not always the case. For rural communities, the majority of laborers may not be locals. Regardless of the location, a casino can help boost the local economy through tax revenue.

Casino security has evolved into a comprehensive system involving elaborate surveillance systems that allow casino security staff to watch the entire facility. These systems include cameras in the ceiling, which track every table, window, and doorway. The cameras are adjusted to focus on suspicious patrons, and video feeds are recorded for later review. Moreover, slot machine payouts are determined by computer chips inside the machines, which are not visible to the public. In a casino, security measures start with these systems.

In the 21st century, casinos are often owned by real estate investors and hotel chains that have more money than the gangsters. Some of these investors, including Hilton hotel companies and Donald Trump, have bought out mobsters and have successfully run casinos without mob involvement. This trend continues today, thanks to federal crackdowns and the fact that the gangsters can no longer profit from their casinos. In addition, losing their gaming license discourages the mob from getting involved.
