Why did the millionaire pose as a beggar in the lesson the model millionaire?

In "The Model Millionaire" by W. Somerset Maugham, the millionaire poses as a beggar to test the character and kindness of the protagonist, Hugo. By disguising himself, he can observe how Hugo interacts with someone he perceives as less fortunate, ultimately revealing the true nature of Hugo's character. This act serves as a commentary on appearances and the value of genuine compassion over superficial judgments. The twist at the end emphasizes the importance of understanding and kindness, regardless of social status.
