The raging demand for bilingual skills is employer driven, not immigrant driven.
Bilingual skills are difficult to learn. But the government isn’t the institution that drives it. The business world always strives to add more value to their products and services.
Although companies try to add technically savvy employees, of the highest and higher levels; non-technical companies follow that same curve. They try to find better and better employees. And an easy requirement is the bilingual requirement. This requirement arbitrarily tightens and raises the bar; it gives employers the illusion that they did improve their competitiveness.
The second languages I choose are Spanish, Chinese mandarin and pinyin, Indian Hindi and Japanese. I have a long way to go to learn the first language. But I have time.
