Why do people think people who make more than 200,000 are rich?

I'm not trying to brag or anything, but I saw my parents' tax returns last night (they left them laying on my dad's desk and I went in his office to find something) and they made like 470,000 last year. But I don't feel like we're rich at all. My dad has a Toyota that's like 5 years old and my mom has a Honda and we live in a modest house. They buy relatively inexpensive clothes and refuse to shop at fancy stores. My mom loves to hunt for bargains and stuff, too. They got me an iPhone, but they still like to have cheap flip phones. The only thing my parents splurge on is my education (I go to a private school) and sometimes on vacations we stay in nice hotels once in a while. Why do people think people like us are rich? I feel like we have a really normal life (not out of touch with reality).

What's the difference between an 'unkown' caller and 'no caller ID'?

This unknown number keeps ringing me, and i thought if someone blocked their numbers (on iphones) it comes up as no caller ID so i'm not sure if it is still a blocked number or a number that can't come trhough.
But when i answer nobody speaks and they've rang one of my friends so its not a scam phone call

Added (1). also they don't speak at all so if it was a company of some sort they must of spoken so its probably a prank call but i wanna know the difference to make sure.

HOW TO ACTIVATE AN IPHONE IF ITS STILL ATTACHED TO PREVIOUS OWNERS CONTRACT?

My aunt gave me her iphone 6s plus because she broke it so i got it fixed, when i went to get it activated for me the guy at sprint said its still attached or connected or whatever to her contract/phone plan, therefore he couldn't activate it for me. I have NO Way to get in touch with her AT ALL, so please don't tell me to call her and tell her to cancel her plan. What ELSE can i do myself to be able to activate this phone with a new sim card and number and everything? I have the apple ID and password to the phone, because everyone in the family uses my apple id, so if that helps or has anything to do with it, i just wanted to make that clear. So, i can't get in touch with her, she's older and doesn't really know how to deal with anything so even IF i could, she probably wouldn't cancel the plan anyway, but i DO have the apple id and password if there's any way i can make the phone work through icloud or find my iphone or something, as i've read articles saying that it's possible, but i don't know if those articles are about the same situation i'm in.

Iphone 6 is stuck on the sending bar?

It's been three days since I send imessages and regular messages and it sends the message to the person except that they get the messages and the message bar is stuck there and then I exit the app and I go back and the messages aren't there anymore and its really getting on my nerves. I already did network reset and phone reset is my phone broken?
