Every human being posses a set of unique characteristics, like voice, finger prints, eyes (irises in particular). Show business is a very developed industry these days with a cutthroat competition and strict rules. As all he voices are unique, all the singers that are well known possess so to speak a copyright to their voice. The greatest singers, the most popular, or the legends of music industry value their voice and price it very high. It is not too hard to find two alike, but still different voices, the rest can be easily fixed with modern computer software.

One of the important disadvantages of sole proprietorship is that it fully depends on the person it is registered to, as if it is a part of that person.

Equal Pay Act of 1963 has been signed by John F. Kennedy in order to maximally eliminate sex based wage discrimination in the US society. The main goal of the was to minimize the wage gap between working male and female population and their earnings. As with any project there were problems with this Equal Pay Act. The Job titles were changed or created different ones for men and for women and different wages were applied respectively. Some people went even as far as to argue if both genders can do all the tasks equally the same way, this thought received a lot of attention. However, even to this day there remains the difference in wages for women not to their advantage. Overall, this act has improved the income situation comparing to the times when it was just signed. It is still argued if the existing wage gap between male and female employees exists until now due to the nature of the difference of the lifestyles and societal roles or it is still existing blunt discrimination.
