Judging by context, I assume he's responding to a fan's request for him to offer some type of merch?
It is disappointing to see that Justin, who makes some of the most entertaining videos of all the vloggers I watch, seems to be performing among the worst financially. Clearly the YouTube algorithm values quantity over quality.
That said, just because someone is good at something doesn't mean that they can turn that thing into a career. I find it a bit gross when YouTube doesn't quite pay the bills and vloggers resort to e-begging to subsidize their lifestyles of leisure (even more gross when those YouTubers are already sitting on a fortune -- which isn't the case with Justin). As much as I enjoy his content, I feel like it would be more responsible for him to get a "real" job to support his family and dig himself out of debt.
