Yes, celebrities should have the right to open a small business. The U.S. with its economy allows anyone to create their own business despite social status, religious affiliation, race, or gender. The individual or group of individuals should be allowed to make their own business as long as they have the money to start the business and maintain it. As long as the business is legal and doing everything legally they are in their own right to make their own business.
Yes, we live in a society that encourages entrepreneurial efforts. Celebrities often make a great deal of money through their jobs. Why not take this money and invest it in small businesses? It's good for the economy. They create jobs. I think this is a better idea than having all that money just sit in the bank.
Yes, celebrities should open small businesses, especially if it brings them joy. Just because they are celebrities does not mean that they have no other passions. This is a good way for many people to give back to the community. They should give some of their profits to charity to help causes they believe in.
No, celebrities should not open small businesses. Jeffrey Morgan and Paul Rudd are very successful celebrities who have much more on their collective plate than dealing with the day-to-day workings of a candy shop. It is fair to assume that this is a passing phase and that the candy shop will suffer from their capriciousness.
