I think the questions you pose in the title and in the main body of your message are different ones.What if EY goes bust? Well, Arthur Andersen collapsed and before the event many people doubted it could happen. EY has its fair share of lawsuits hanging over it today, but closure due to massive brand damage seems more likely than closure due to running out of money (i.e. going bust) per se. If it happens, the sheer force of numbers of people changing employers will mean your CV wouldn't stand out. Again, look at what the thousands of people at Andersen did - they've now blended into the ranks of other firms.What if just the advisory business line is a flop and EY retreat from consulting? Although EY will have done their research before making a move to set up the business, there is always an element of chance in these things. No matter how much money they throw at it, if they cannot attract good consultants, scandal strikes, or the whole market declines, they could retreat quickly. Also, if the rumours are accurate that they expect to make a profit independently within 2-3 years, there is a fair chance they will be disappointed and as a result decide to pull back. Wholesale closure of the Advisory services line is unlikely under any of these scenarios is unlikely, if only for PR purposes. More likely is that the service offering will be curtailed, it will lose independence and be brought under the control of audit & assurance, or will be allowed to shrink into a niche.
