I completely agree. I made the mistake of taking a lower paying job in a lower cost area at the start of my career. When I did move to a higher paid area, I found that new grads were almost being paid my rate.
Same. The comment was a reflection of my observation from Plano -> SF -> NYC. I started my career in Plano. I personally was able to grow a lot more in my career after moving to SF (and later NYC).
