Yes, that is obviously true. I knew it when I came here but was maybe a little blinded by the fact I had a free place to stay for a couple of months, and probably had illusions of slightly higher salaries than is the reality. Thanks for your PM, I will reply also.
er2; yes, I had a job interview out at the HKIB in science park. Apart from the unis it is probably the only place to find science jobs here, but even then, biology doesn't feature as heavily as physics and electronics.
