Are piggy banks still relevant?

When I was at Target earlier this week, an endcap of piggy banks caught my eye. At first, I thought, "Oh, how cute." But a few seconds later my mind was all a sudden screaming, "Wait a second! Where is the relevance for these today!?" I began thinking this as I noticed some piggies had "vacation fund" painted on their side.

Do people still long for a place to store change and dollar bills?

How would you use a piggy bank if you had it?

Are piggy banks treasured by adults the same as children today?
