Yep, when they hit their 30s the whole cute "gamer girl" thing wont pay anymore. Suddenly realising they should have focused on a career with longevity.
And if they have good sense they'll have enough money to buy one.
Of course most won't because they'll have failed or succeeded and then blown the money because people tend to spend what they have and especially so when they somehow acquire a large at least semi-regular income in early adulthood.
Let's say one of these deceitful porno people (it's porn, albeit not very good porn, and it's deceit because it's being passed off as something to do with gaming) makes an average of £25K a month for 5 years. That would be possible. Of course most people trying it will fail, but from those who succeed those figures are possible. It could be a lot more if they're really successful and it could carry on for longer, but I think those figures are more likely in a successful deceitful porno career. Keep £2K a month for living, save £23K a month. £2K a month is more than most 18 year olds can earn legally, that's for sure. Keep it up for 5 years and that's £1,380,000 saved. Presumably there's some tax, but there are ways around that to some extent. Someone who makes money from deception is hardly likely to care about doing as much tax dodging as they can get away with. Also, the money being saved should grow to some extent from interest or safe investments. They should have at least a million in spare money by their early 20s. You can buy a career with longevity with that much spare money. The obvious one is rental property owner, but there are others. Also, because of the deception about their sex work they won't have the stigma of honest sex workers so they'll have less difficulty transitioning into other work. Maybe get a job on TV, for example.
