Part of the reason that I'm staying is because I'm in a tremendous amount of debt and therefore I've become extremely paranoid and risk-averse. Part of the reason is that said debt has me working a second job and I am in a largely-dysfunctional relationship besides, so I have very little energy outside of this job. Part of the reason is that I have gained 80 pounds and no longer fit into any nice clothes for a job interview, with very little chance of me getting anything nice any time soon.
Man, that paragraph makes me sound like such a downer. I promise that I'm really happy and easygoing most of the time! That's just the more-sober reality of why I find it a huge struggle to jump onto some new thing.
Where I live in a rural small town, I make top 5% tech salary (~80k$ canadian pesos). The same salary in Montreal is probably 25-30 percentile of tech salary? In Vancouver it probably would be 45th percentile of tech salaries. That said a the price of a Vancouver condo buys a Montreal Duplex and buys a whole New Brunswick suburban sub-division... Or a mansion with a few acres on the sea front and 5 bedrooms / 7 baths...
I'm doing an apprenticeship starting when I was 17 year old and I only earn $11K (I don't pay income tax because it's so low) and yet I managed to save up 8k because I live with my parents right now and except maybe buying a car I don't even know what to spend it on.
For context rent is here at about $400/month for a single bedroom apartment. Another $300/month is enough to cover food and utilities for at least two people.
Unless you want to retire in san francisco or some big city there is no real advantage to buying a home there. So are you buying a new tesla every two years? Are you buying a macbook/iphone/high-end gaming pc every month? I honestly have no clue.
EDIT: Maybe I should also mention that the company will pay me at least $30k/y after the apprenticeship.
Houses: 100k-1mm
Cars: 15-80k (each)
Vacations/Travel: 2-10k/year
Expensive Clothing: $3-5k/year
Jewelry: $0-5k/year
Hobbies: $1-20k/year
Entertainment/Dining/Drinks: $1-20k/year
Retirement & Other Investments: $0 - 50k/year
Repeat some of that stuff for their children, add college expenses, maybe private school.
Those are just some examples that I largely based off of my sister. She is constantly expanding/improving her home (bathroom remodel and new pool in the past 18 months), she loves big expensive jewelry, she has designer purses and clothing, they have 4 cars which all have TVs and other fancy options in them, they have a class A RV, her husband builds cars & races at the track, they have young boys and everyone has a dirtbike, boys have modern toys/video games/etc.
You might think "wow, that's ridiculous," but really they're just spending to their level of income. It's pretty common.
You, on the other hand, seem to be more like me. Of my salary I'm required to spend 8.2% on my mortgage, so I don't default. I've started a homestead that I've been buying a lot of tools and equipment for. My utilities come out to another ~1.5% of my salary. Everything else is savings, and/or thrown on to the mortgage. I'm going to pay my mortgage off fully in ~18-24 months (total time). I have no other debts and after that I can save 100% of my salary. I'd like to maybe build a new home on this homestead someday, but I'm not going to go into debt to build it. In the meantime, the salary affords me the luxury of no financial concerns and the ability to help others when they need it.
If I had no debts or ambitions to own property, and I didn't mind living in a small single bedroom apartment like your example, I would spend the $700/month on my living expenses and save the rest. I'd probably dip into savings to visit another country each year. I'd retire early.
In the end, that's your real answer. Savings & retirement funds. You just haven't thought that far ahead because you're very young.
I have a Toyota. I don't need a Tesla.
I am a (relatively) happy person.
What more could I want?
One thing that I have noticed at my own school is that many of my peers undersell themselves and don't even apply to the highest paying companies despite being very qualified.
