What are the benefits of doing a Arts/Law degree compared to just Law?

I am not sure about exectly which type of law, but probaly NOT crimminal or business law.

I am doing this special thing where I am doing an undergraduate Philosophy degree in Year 12, so I can transfer credit and finish the Law degree faster. Should I go for it?

What are the benefits over just Law?

With an added Art degree, you'll make a much better socialite if you make a ton of money in your law practice.
