The chains want you to believe there are tons of jobs so more people will go to school and the increase in supply will help drive down demand and their costs (i.e. your salary).
The schools want you to believe there are tons of jobs so you will pay them $30k+ a year to go to school.
Some current pharmacists want you to believe there are no jobs to keep supply low and demand (and wages) high.
Baby Boomers are going to start retiring next year and more jobs may be opening, though some may have lost everything in this economic downturn and may stay working long into their 70s.
As with anything the reality is probably somewhere in the middle. Depending on where you live, the population, the age distribution of the population, the proximity to a pharmacy school, etc. jobs may or may not be available and the pay may be good or bad. Look at what jobs are available now and expect things to be similar 4-6 years from now, but be prepared to have to relocate, especially if you want something specific.
