Is security a job that people look down upon?

My younger brother is 20 years old this year. He has not gone to college since graduating from high school. It’s not that I, a sister, can’t support him, it’s just that he has a fun nature and can’t even get into college. I had no choice but to let him find some small jobs in his hometown town. Anyway, he was still young and there was no harm in exercising. But recently, my mother drove him to live with me because he didn't do well in the town and started fighting in gangs. Helpless, I had no choice but to arrange for him to stay at my house. Although my husband has some minor objections, he doesn’t dare to make even the slightest joke with me since I’m so serious. Two days ago, the community property management suddenly posted a notice recruiting security administrators (also known as security guards). I just thought that I might as well arrange my brother to work in the real estate industry first, so that he can get familiar with the rhythm of life in the city and learn to deal with city people. My brother is tall, 178cm, and has a strong figure. The key is that he looks good. To use any fashionable word, he is stunningly handsome. Haha, I applied for the job very smoothly. In this way, my brother officially started his life in the city. I was stunned, and so was my brother. Angrily and helplessly, I turned to my colleague and said, "He is my biological brother!" My colleague was also stunned and did not apologize. He turned around and said: Okay, see you tomorrow! Just took a taxi and left. When I got home in the evening, I saw that my brother’s face was not good either. During dinner, he said, “Sister, why do people in the city look down on my job? Do they all regard us as watchdogs?” I suddenly I cried, touched my brother's head and said: "Those people are all ill-educated people. In the city, you can get the top prize in the 360 ??industry. You don't have to think that your position is despicable. As long as you work hard, You will succeed wherever you go." My brother nodded, had dinner, and went back to the house.
