Gambling has been a part of human civilization for millennia. Archeological evidence shows that wooden blocks were used in games of chance in 2300 BC China and dice showed up in Rome around 500 AD, followed shortly thereafter by playing cards. Casinos are a large and profitable industry, and they have earned a reputation for being places of high-class entertainment, glamour, and excitement.
Casinos require skilled labor to operate and provide service to their patrons. When a casino moves into an area with a lower level of skilled labor, it will likely attract workers from outside the local community. This will decrease unemployment in the area, but it will not have the same effect on employment for the original residents of the area.

While the stereotype of the seedy backroom gambling parlor may still be true in some cases, most casinos are large, professional venues that provide a safe environment in which to gamble, watch live entertainment (or sometimes closed-circuit broadcasts), and enjoy food and drinks. They employ security guards, monitor their parking lots, and take precautions against the crime that plagues some other types of gambling establishments. This makes them a far safer and more palatable alternative to the seedy backrooms that many people associate with gambling.
