Seriously, where have you been in the past several years/decade? If things can be outsourced, they will be outsourced. They can't do it all at once, but they've been doing it continuously and very consistently for a long time.
Do you really think Wells Fargo will suddenly grow a conscience and decide to stop?
Basically, stop asking questions you already know an answer for. If your position is outsourcable, start looking for a new job.
