At my High School, everyone had to take a Computer Science class for at least 1 year.
My year had 60 students and I'm the only one studying CS/working in the industry. I'm pretty sure your, mine and everyone's wage will be alright.
Yes, only an anecdote, but it's not like everyone is switching from their dreams to become a doctor/lawyer/pilot/xyz to a CS job just because they had a HS class.
Does teaching algebra drive down the salaries of engineers?
I think that the learning curve between "able to automate simple things in Excel" and "doing software development as a career" is high enough that it's not going to do much to wages.
