Yes, it really is that high. We require our clients to set the pay upfront based on the global value of the work, and the successful applicant will receive that amount no matter where they live. If they are the best person for the job, it shouldn't matter whether they live in Silicon Valley or Sri Lanka.
Most positions are calculated based on an hourly rate e.g. a $100k role = $50 per hour x 40 hours per week x 50 weeks (assuming 2 weeks of annual leave as a baseline, though self-employed contractors have the autonomy to plan their own vacation schedule).
