Always, always, always ask for more! The worst thing that could happen is they say "no."
No big deal! I've had lots of pharmacist friends go in and ask for 3-5$ more an hour and they end up getting close to it! Each 1$ more per hour = 2,080$ a year! Not to mention if you get standard % raises, you have now just gained even more compound growth.
1$ more per hour with 3% annual salary growth = 6400$ more per year at year 40 alone! With over those 40 years, you would gain 150K more. Just by asking for 1$ more per hour, assuming annual 3% growth.
3$/hour more = 450K over 40 years
5$/hour more = 750K over 40 years
