G type stars are fairly long lived, and last longer than the age of the Galaxy.  More massive stars are much more luminous, thus easy to see with our eyes, but they are also spendthrifts, rapidly depleting their main sequence hydrogen supply.  Most of them have long since turned into supernovae and collapsed, so only the newest are still evident in our region of the Galaxy.
