You can fly jets domestically beyond 60, and a significant number do.
That gives you at least 2 full decades in the industry, more than enough time to make to a command on a wide body jet that probably doesn't even exist yet, and on the way ride the ups and down of a career, spending patches unemployed through times thick and thin.
Many of my crowd went from begging for a C206 job to narrow body jet command in 10 years, and that was including some very lean years including 2001. No reason why you can't do that too.
Flexibility, willingness to relocate and a supportive partner will help massively.
