There are many lawyers and law school grads right now unemployed, so I wouldn't consider that path based solely on money. Rosalind is right, there are few vet schools in the country and getting into them is very tough (we have one of the few here at OSU). So you will want to make sure it's what you want before entering into a program.
There are so many options in life, each one requiring a different educational path. Sometimes you go in with one thing in mind and end up in a totally different place. A man I know is the custodian of the local theater (the kind for plays, not movies) and is also a playwright. He has found that it suits him to do something that just pays the bills during the day and leaves his creative juices for his own work. He'll never get rich, but he is very happy and fulfilled. He has no children, is single and doesn't need much to get by. Another friend of mine has a PHD, is a music professor and barely scrapes by but has a child so she finds the financial constraints very stressful. What's right for one isn't right for all, you need to do what's right for you.
Be careful to not incur college debt with no purpose, there are lots of new grads (many with general liberal arts degrees) drowning in student loans unable secure jobs right now. They are shocked when their degree doesn't mean what they thought it would.
