You make it sound like not having DST is terrible, but most of the world doesn't bother with it.
It's basically Europe, the US, and a few random others including half of Australia for some reason. Everyone else gets by just fine without DST, and much of the world gave it up when they stopped being colonies.

Maybe it's time to think about the hours we do things in general. For example, in Japan most shops don't open until 10 or 11 AM, and stay open until 7-8 PM. That gives people the opportunity to visit them after work or school. Schools and employers set opening times based on local conditions, because there are vast differences between northern and southern climates. It turns out that everyone doing what makes sense for them works just fine.
With things line linear TV and radio becoming less relevant, times also matter less. It's a good thing, it gives us flexibility.
