No doubt he probably could support himself, but his costs go way up if he is also supporting a younger wife (babies) who does not have a job. If streaming is the only job between them, he would have to make a pretty good amount considering he has to pay for things like health care out of his own pocket (just one example). It also depends on the type of lifestyle they live as well as where they live. Some families can get by on $20k a year, some can't get by with $100k. Just too many variables IMO
