I looked up this MegaCapitalG person, their estimated (not to mention likely inaccruate) earnings for the year are $3.4K - $27K. I dunno where you live that $27k per year is a lot. $27K/yr isn't even minimum wage, teachers earn more than that. Even when I was earning around $29k a year, after 2yrs I was only able to save up roughly $30-35k in total which was spent on a car.
In 1yr I'd spend:
$4,800 on board
$350 for my phone bill
Average $700 for fuel.
Average $3,400 for lunch/food
Rego $600
Insurance $1200
So in 1yr even living at home with my folks I had spent $11,000 that left me with $18,000/yr. This isn't even factoring other activies I spend money on either; as well as other items I purchased throughout the year.
Even if I was earning $100k/yr after tax I'd still not be able to afford to move out of my home for roughly 6-8yrs.
Now imagine if I had been living alone.
I don't overly see an issue with YouTubers starting kickstarters mainly because if they're doing it for the wrong reasons; I'm not the 1 dumb enough to give them money, but kickstarters are meant to be for projects not medical issues or things like that. A YouTube channel counts as a project to me and if they're not getting by and need to keep it running then they can start a kickstarter, obviously if they don't live up to what's promised they're burning themselves, I'd personally rather let me channel crumble/leave than ask for money, but those are out of my own personal morals. I do however, have a bigger issue with people that assume YouTubers fart money out their arses and can afford to do whatever they want.
