Explain value of earning vs being given?

My ex is bribing our 17 yo with money, new truck, no rules, 4wheeler, new iphone and tge list goes on. I have tried to show my kids that if you wabt something you should earn it. I want my children to have morals and integrity but i can't make him understand that he should finish school and get a job and work for those things. Thats how responsabile adults get what they want. How do i explain by enabling him she is hurting him in the long run? I told him to remember that whoever gives you something also has the power to take it away or say if it was not for me you would not have that but he thinks i'm wrong and being mean. Advice on explaining or dealing with this situation?

Added (1). Sorry for poor punctuation and typos. I'm using an old phone with a tiny keyboard while my other is being serviced.

Why do people put their iPhone opposite when they are not using it? Read details please?

I know my question is silly but trust me i'm curious. My question is why people keep their iPhone opposite way like on the table. I've seen my colleagues, friends and even my teacher who own iPhone they put their iPhone's back screen up i always have this question but feel embarrassed to ask cz i know its really silly i'm showing you the position in the pic just ignore the case of an iPhone. Why only iPhone not any other phone? Is that to show off? Or to show apple's logo? As i'm unable to upload a pic here i'm sharing a link kindly open it and check.

Why doesn't my selfie stick work with my iPhone 6?

It's the kind of selfie stick that works by plugging into the phone audio jack. It works on my moms iPhone 6 but when I use it on mine, Siri starts taking or it says voice control and it doesn't allow me to take the picture when I push the button on the selfie stick. I should add that it sometimes works. But most of the time it doesn't. Usually, it works once and then when I push the button again to take another picture, Siri speaks or I'm prompted to voice control. Does anyone know how to fix this problem? Is it something that can be changed with my phone settings? Or is it the selfie stick? The selfie stick isn't an expensive one, I bought it at Señor Frog's while vacationing in Mexico. The instruction manual only explains how to place the phone on the selfie stick and nothing else. I would appreciate some help!

How to make your number seem disconnected without disconnecting?

I have an iPhone and I know I can block numbers simply from my device. I know when you block a number this way they can text and call as usual but it won't go through to my phone. IIm just curious to know if there's any way I can permanently block someone so it's as if I have changed number or disconnected my phone. I don't want this certain person thinking I'm getting their calls or messages I want them to think that I don't have the number anymore at all. Is this possible? Without changing my number.
