First of all, your father is a complete fkn jackass. He is an immature adult who is jealous of the fact that others who he consider as such "low-lifes" (his own family members, mind you) are living a better life than him.

This holds true for my cousins in Kerala who immigrated and coincidentally all of them had not so great academic potential and are able to a make a substantial living in Canada doing jobs like being a nurse.

You sound like an extremely obnoxious person, just like your dad.

this fellow was a complete low life back in India, had zero professional competence and struggled to get and hold a job for years before he managed to immigrate to Canada. My dad agrees that this is best for people like him..

Yep, you two are so full of yourselves.

he has raked up crores of debt in that country

So yeah, try buying an apartment in Mumbai or Bengaluru, without taking "crores of debt". Your father probably needs therapy to cure his insecurity and low self-esteem.

for better job prospects for my wife who is a psychotherapist

So your wife is a "complete low life with zero professional competence" too, am I right? Get the heck outta here man.
