Depends on the exact nature of your question. If you want to argue on simple moral terms, both are wrong because stealing is stealing. But the "wrongness" of each action can be debated so obviously under most legal systems the punishment is not identical - and that is a related but a different conversation. But note that the punishment for stealing, in most cases, is not dependent on the personal wealth of a victim. I say most because I'm sure some pedant is going to find the odd outlier.
