I'm on iOS 7 and I'd like to make the folders' background transparent so I can see the wallpaper behind it. Is there a way to do this?

You may have turned on Settings > General > Accessibility > Increase Contrast
which increases the contrast for areas including Unlock Screen/Notification Center/Control Center/Dock/Folder Backgrounds.
Without a jailbreak : No.
With a jailbreak : Not possible either. There is no jailbreak for iOS7 yet.
