Dogs DO like their crate if it has not been used in an abusive way. It is their nature to want to retreat to a smallish, enclosed "den" type of shelter to rest. Unfortunately, stupid humans are able to twist this normal inclination. "Gee, he likes to sleep in the crate for several ours at a time. Why not just lock him in while I leave the house for 18 hours at a time?"
