A good bias network fixes Ie at a specific value. Then Ic = alpha*Ie. Alpha is hfe/(hfe+1). Alpha varies a tiny amount, from about 0.980 to 0.998, while hfe varies maybe 50 to 500. As posters have stated above, negative feedback neutralizes variations due to hfe, temperature, gm, Ies, Ics, etc. Good bias network design results in an amp stage whose performance is consistent and predictable despite parameter variations for individual parts as well as temp and operating point.
