Consumer rights
Consumer law is often overlooked when students are thinking about how best to make a difference in the world. However consumer issues have an enormous impact on many people's lives whether they be disputes with utility companies, credit card debt, aggressive debt collection practices, unaffordable hire/purchase agreements or tenancy issues to name a few.
A law degree is not necessary for many jobs in consumer rights (though it can be an advantage). If you are unsure of whether to study law, or are not sure that law school is the right place for you, there are still careers in this area open to you.
