If by "very comfortably" you mean having a car, and all those other amenities that you mentioned, no need to poll everybody can figure out the answer already: no.
But "very comfortably" differs from person to person. What one thinks is very comfortable is not your idea of very comfortable. So just agree to differ lor.
Anyway like I said, if we use your definition, then no need to poll we all also know that it's not enough.
