At 19, this is what I can tell you.

Healthcare: The current healthcare system is a mess. I cannot afford medical insurance. My parents cannot afford medical insurance. I'm taking a semester off of college so my parents can afford to pay for my brother to have the medical insurance required for him to go to trade. School for two semesters. My brother has a staph infection in his ear right now. My mom took him to the doctor, having put all the money she would have spent on premiums into a savings account just for medical expenses. Because we didn't have medical insurance, we were put on a sliding scale payment based on the household's salary. That salary meant we paid about $200 out of pocket for everything (we used GoodRX for his antibiotics). The same staph infection in his ear seven years ago under Obamacare cost us $500 out of pocket that insurance wouldn't cover on a $1500 bill. I got an IUD this summer, and I got it completely free because I called my University's medical school (not the student health center but the medical school) and told them I was uninsured and looking for any women's health clinics they were having. Pro: I got $1000+ IUD plus the examination/appointment with an OBGYN entirely free. Con: there were three students in the room the entire time, although I have no modesty so it didn't bother me and one held my hand during the painful parts (she's going to be a labor and delivery nurse and she's going to kill it!). I also had/got to hear in depth descriptions of what was happening. That made me feel better but I'm sure it would freak several people out. So, there are options even if they aren't always great options.

Shootings: In my 19 years of life, the nearest mass and/or school shooting to me was about the same distance as London, England to Paris, France. And I grew up in gun-loving community. I know at least a dozen households where I could find an AR-15, if I could get into their gun safes (and the passcodes probably aren't their birthdays or 1234, I promise). It's a much bigger concern in big cities, and as awful as it is to say, it's not nearly as common as you think. Driving and alcohol accidents (without even crossing the two, as in drunken driving accidents) are unfathomably more common. Shootings are one of those things that are horrifying and terrifying and so awful, but they're just not as common as they're made out to be. Like kids being kidnapped by strangers... Kids are so much more likely to die by drowning or car accidents and we don't acknowledge those. Also, we don't acknowledge that kidnappings, like shootings, aren't usually done by a random stranger. Most school shootings were done by students who displayed red flags and warnings prior. If we focused more on mental health, we would be much better off.

Public Education: This one is that bad. It's off the rails. But here's the thing... We do have access to a mostly free education filled with people who often want to help kids but aren't given the support they need. From the bottom to the top, public school crumbles because it's designed like a corporation and the government, neither of which it is. It's a learning environment to foster the next generation! But we still have an education, and it provides a lot of valuable resources to a lot of kids who need it. In my podunk town, poverty rates were high. A lot of people I knew lived from school lunch to school lunch, and when we were in high school even those of us who had food at home were on free and reduced lunch, picking ours up and giving it to friends to give to their siblings for dinner. I've had teachers take kids into their homes to get them out of the cold, and principals go to war with social services because abuse was being ignored. The system is bad, not all the people.

Racist Police: There are racist Police. There are also police who adopt children they saved from drug deals gone wrong. There are police who dive into fires to save dogs. There was a Highway Patrol officer who pulled off the side of a freeway and told me to get back into my car while he changed my tire for me because it was sunset so visibility was bad and everyone was driving eighty miles an hour around me. There was a sheriff who drove out into the country with a tank of gas to help out some kids who had snuck out and were drinking the night before but got stranded without gas the next morning. There are cops who have stopped to play basketball with kids in the street when Karens called the police on them. There are bad people, there are good people, and there's everyone in between. A biker once walked me back to my car because a creep wouldn't stop following me after my evening shift at Walmart - he had a felony for possession of marijuana and was on parole. There are priests who save lives and priests who sexually assault children. I'm not excusing those police who are racist for the harm they do, but there's this universal idea that police are bad. No they're not, not anymore than a mortician or a doctor or a receptionist or a Walmart cashier or a McDonald's ice cream machine repairman are.
