Beyond the over generalized statement that racism was invited by white people, there is nothing wrong with the book.
If it’s really for 4 year olds, even that statement might be fine rather than delving into the complexity of what systemic racism is, and why it can exist against white people in other nations where they are a minority.
Simplifications happen all the time in books aimed at preschoolers. For example, they would usually teach that America was “discovered” or that Native Americans and the settlers got along in thanksgiving harmony and nothing else.
