Actually, my parents had no choice in migrating ... they were "displaced people" & had to find another country to live in. I think their aspirations for me, if you could call it that, was because "betterment" was so possible! So easy, in fact, compared to the set (European) society from which they had come. Oz was unbelievable!: you could work hard & you could profit & improve your life. I have noticed a very similar attitude in many of the Vietnamese students I've taught.
Strangely, the most stuck, bitter & resentful students I've taught have been the offspring of Oz "battlers". It is hard to understand why, but many totally lack drive, inspiration, hope ... some of those students come close to breaking my heart. It is so hard to motivate them, to convince them that learning is worthwhile ....
