There are number of classic failure modes for Scrum. One of them is to not have a Product Backlog at all, or to only plan it out a few weeks.
Since you claim that in your experience, Scrum de-emphasizes forward thought and big-picture thinking, I can only conclude that you don't do this, and have decided to blame Scrum for this fact.
I suggest that you identify whatever it is that is preventing your team from creating a full product backlog.
