The problem is that in the end the money has to go somewhere or be spent (why else steal it?). Also to live a legal life (house,car,boat) you have to have a source of income/spending that does not set off red flags. If you are a high paid bank employee why even bother? Many (most?) financial type crimes have no statue of limitations so to get away you literally have to get away with it for the rest of your life. The other side is even if you get away you will spend the rest of your life wondering if today is the day you get caught. To be honest I think that is why so many white collar crimes are so brazen looking. I think they would rather go to jail for a few years be done with it and live the rest of their lives with the money they have "lost".
Unless you live in a country like Russia where stealing money from the US is basically legal. Then go for it.
