Both businessmen and entrepreneurs are important to the economy, but there're lots of difference between them, like in their approaches, mindsets, and definitions. Businessmen definitely focus on managing established companies and targeting success, whereas entrepreneurs pay attention to innovation and taking risks to create new ventures or transform existing ones.
Agreed because this is a perfect summary of the difference between their two, a business man won't want to take on new risks because they already have a system that's working for them hence all they're concerned about is how they're going to improve their business through the same system that has been working for them for many years but an entrepreneur is willing to take on new risk despite how many times that he tries and fail because an entrepreneur is more about bringing solutions to problems in a newer way or improving drastically on the already existing solution and making it better.
An entrepreneur pushes boundaries and not allow himself to be contained with in a box but a businessman won't mind repeating the same thing over and over provided he's making money and not taking on too many risks. Without entrepreneur new technology won't be invented and new ways of solving our problems won't have been found. We need more entrepreneurs in the society than businessman.
