Well, according to your details, you're something having to do with an "rj." My suggestion is you ask one of your solo FAs. You may or may not want to get back to me after that.
Not only have I asked one of my solo f/a's, I'm pretty good friends with several of them. Not only are the people pretty good most of the time, most f/a's at my company prefer to fly the 200 so they don't have to deal w/ another f/a. That is pretty telling that they'd rather work harder with the pax than deal with another f/a. If you are a wide body, international flight attendant, I could see an issue every flight, but for a skyw f/a, not a chance. Most flights will be a short duration and they are on-time most of the time.
In my opinion, the quality of the f/a is the biggest factor. I have had multiple flights where people have walked out and dang near everyone thanked the f/a by name and said what a wonderful flight. I have also had other flights where people walk off and don't say much. Some locations tend to have more difficult pax (NYC) than other areas. Of course when you are late, or have mx issues, or divert, then that causes problem with pax, but on a normal flight where the weather is good and the plane is on-time, there are very few problems.
Don't over dramatize the situation. If you are experiencing 'difficult situations on virtually EVERY flight' that an 18-20 year old is not mature enough to handle, then perhaps you are part of the problem.
