No not true.
The world is getting safer every generation. True there are hot spots and riskier places and times but in general on average the world is getting safer.
What is happening is mostly the unseen, instead of dying on farmland in a farming mechanical machinery accident or in a factory or from lung failure from dust, you're mostly dying old in nursing homes or at home and none see that apart from usually women who care. The urbanization, TV and proximity is making the event you didn't see into one you do see.
Also bear in mind in a democracy, the candidate who says the world is better is not voted for, the one who says it is bad and you need to vote for them to make it better is voted for, given also news is paid for via commercials a really bad world makes the few richer.
I do 3 things differently:
I do not watch USA TV. USA TV makes the world appear worse than it really is. The billions of small acts of generous gentle kindness is no-news and the few bad incidents are broadcast widely, with the "messages from our sponsors".
I do not drive. My getting about is via bike, I have beautiful sunsets and sunsets and rides with the dears and squirrels and the blossoms and now in winter the smell of wet earth and green.
I pick where I live, who I work for to avoid issues. That takes decades.
Shoot an arrow and walk to it where it lands. Repeat. Life is a journey not a destination.
If USA had to one thing different is to become Canada. Debate, disagree, less guns and less negative angst.
