ELI5: Why does daylight savings time end in the fall? Wouldn't a constant shift in time to make more daylight in the evening be best in the winter as well?

Mainly because we need some light in the morning. In winter, sunrise can be as late as 7-7:30am already, pushing it back past 8am can make it dangerous for kids walking to school for example. 

The other thing is most of the pros for summer DST are things like people staying out later thus increasing business, but people generally don't want to stay out late in the cold anyway.
