Glassdor.com has published a report on Software Engineer Salaries at the 15 Top Tech Companies:

Of the 15 tech companies in this report, Google Software Engineers earn the highest average base salary for 2012 ($128,336). Trailing closely behind are software engineers at Facebook ($123,626), Apple ($114,413), eBay ($108,809) and Zynga ($105,568).

They also report that the national average software engineer salary is $92,648. So, the average Software Engineer still makes less than the average Lawyer, Pharmacist, Doctor, vice president, or (much less than) Banker, but more than the average manager, accountant, or business analyst.
