It is a sad state of affairs, anywhere, because sadly it's the same in most countries. Unless someone is headhunted into a high-level job, it's usually "start from the bottom".
It's also sad that there is a resource of people not utilized for their skills. An update in credentials may be needed in some jobs, but they shouldn't have to be set in a way that people, in some cases experts in their field, fail.
You figured it out fast that this wasn't for you. Nothing wrong with that.
I couldn't respect myself if I had given up. I'm too stubborn. Sometimes (that's a lie. "Most of the times" is more accurate.) my stubbornness kicks me in the butt. This time it paid off.
Below is my personal opinion and my observation; it might be a bit harsh.
Given what I saw in Canada, I can see where this is coming from. I had faced discrimination and racism almost everywhere I turn my face (Immigrant, minority, with a disability). Personally, I do not think anything will change in the near future, and the amount of "Reversed immigration" that is taking place is very very concerning. Many of whom I know left Canada the soonest as they could. They believe that safety is an issue, while renovation and evacuation are taking place, and try to convince you that we have a "universal health care system", in which you need to wait 24-48 hours at the hospital's ER is normal, is beyond them to tolerate and call Canada "home"; most were concerned about raising their own kids as well.
I really hope Canada addresses these issues before the immigration scheme fails to attract REAL IMMIGRANTS (not students from South Asia who mostly are coming as students, with the intention to overstay and work, in massive numbers, causing a reduction in minimum wages, increased cost of living, increased rents, and worst, they bring their issues with them...Just think about how Walmart, KFC, Mcdonalds, and similar organizations hire and operate frequently, try to fit in if you're not from South Asia).
I have nothing but respect for every individual, but if Canada doesn't address these issues, maybe one day, no one would move to Canada in the first place. Canada is aiming to become a "melting pot" for immigrants, and I guess this goal is far-fetched, while the demography continues to change towards specific immigrants from the world (India+China), it'll be next to impossible, to settle
Unfortunately, once you attempt to settle, it is not easy to return back.
I don't have hatred towards anyone, but if these issues aren't addressed; it'll impact each and everyone in Canada. If we don't mention these issues, how would officials know, right?
I am considered a minority where I am; this is causing my issue to be way more complicated, and I feel a bitter taste in my mouth to say this, but discrimination and racism here are real issues. (Literally, every race discriminates against me!)
With that being said, and despite the above issues, I liked Canada with all its pros and cons, and it is up to anyone to work hard and get back on the track.... Respect is earned, not given.
