No, he's right. The level curve in gen 2 was pretty mindboggling and I'm surprised HGSS did nothing to fix it. It makes the games the worst when it comes to grinding, especially when wild Pokemon are really underlevelled by the endgame. It gets to the point where I typically reach Red with only lv.40's (and a BUNCH of items). A lot of gen 2 Pokemon are also really rare or only available in Kanto.
...Wait, no I don't.
