You often hear the catch phrase, "show, don't tell". There's value to that advice, but don't take it -- or most other advice about a creative effort -- as absolute. Don't break the rules just because you think it's cool and avant garde to break the rules. I've read lots of really bad novels whose goal was pretty obviously more "I'm going to write a story that breaks all the conventional rules" rather than "I'm going to write an interesting story". But don't be a slave to the rules either.

The key question is not, "is it lazy?", but "is it interesting?"

Science fiction stories especially often need a lot of exposition to tell the reader the history and politics and technology and whatever of the story's universe. The trick is how to make it interesting. Consider:
    

> In 2340 the North American Coalition was formed between Canada and the
> United States. The first president was Herbert Fromme. He implemented
> economic policies that helped the NAC to recover from recession. The
> constitution of the new government gave presidents a 5 year term. It
> divided the country into 30 provinces. The province of Nordia include
> the old Canadian province of Nova Scotia and the American state of
> Maine, plus 100 square kilometers of ...

Well you're probably already falling asleep. Why should the reader care about any of this? It's boring.

But something like

> After the brutal North American War between Canada and the US, a new 
> nation emerged from the ashes, uniting the survivors of the two
> countries. As the new united Americans looked across the blasted
> remains of what was left of their civilization ...

Okay, not great literature, off the top of my head, but there's at least potential for interest. There's somewhere you could go with this.
