I'm glad they shut down her lemonade stand. After all, most businesses require a license to do business in this country. There are many reasons for this, the biggest of which concerns public safety. So if a kid wants to open up a lemonade stand, or any other kind of business, I think they should be required to get a business license.
How I think it should work is that anyone who is under the age of 16 should be required to apply for a special business license. This business license should be maybe $5. When the kid applies for it, they are given pamphlets that lists their duties and responsibilities as a business owner, including liabilities and work practices that are safe for them and their customers.
This way, getting a business license can be an educational experience for them when they get older. After all, when adults start a business, they not only have to get a business license, there's also other paperwork required, such as applying to be an LLC or a corporation of some kind. Let's teach them, as kids, the responsibilities and requirements involved in doing sol.
So I say let's teach these kids the realities of running a business and what it takes to start one up.
