"Disintermediation" - what a great word - is one of the defining concepts of the information age. I can tell you from daily professional experience that there are 10 Asians and 30 Indians out there stalking each and every client you have as it is. wehn your business becomes nothing but marking up someone else's services you will last about one internet ping-time.
In you wildest dreams, maybe. How you would wish it to be so, too. Oh, how I'd hate to disappoint you, Andy! (/sarcasm off)
You think my client base doesn't know what's out there? C'mon, why do they keep calling me instead of them? Use your head.
Mine is a business model likely to survive far longer than your career at the rate you're going. Furthermore, unlike your career, where my business is concerned, it will be inheritable. Your career, at this time, likely will die with you, if not before.
Sure, it's a preventable "death." You'll just have to figure out a way to make it so. That's your job.
