nesses that solve real problems are good businesses.
Not all problems are good for business.
Problems are everywhere. Housing, food and health care are essential for people. They are looking for happiness, status and belonging.
Profits can be made when a business has a product that customers want to buy. A business can thrive if it has assets or other ways to sell something at a higher price.
Sometimes, however, a particular problem is not suited to a private answer. Or, the private solution could be something that we all need but is available in many places, so it may not be profitable for a particular entity.
It is unlikely that we will run out of issues. Finding a company that can solve a problem would be a good first step. It also helps if the business is also successful.
