This isn't the case for everyone. In my workplace the time we spend
debugging is small compared to the time writing the code in the first
place. I wonder what the difference is?

We do use unit-testing quite widely, but by no means everywhere. The
code which doesn't have unit tests doesn't tend to be any buggier than
the code which does. Where testsuites really help is when you have to
upgrade some library or service that your programs are depending on,
and you get to find out about subtle backwards-incompatibilities.
