Outside of web development, you can get a job fine without using this year framework. However, you still have to leave after a year to get more than inflation.
This hits home. I've been in software development for quite some time (10 years), I've been with 4 employers so far (full time) and pretty much all my significant raises have come as a result of me looking for a better paying position and then leaving. I may have been unlucky (I also did not work for a really large company yet), but I feel like the "career develoment" opportunities within software engineering companies are way under the level they should be.
Each time he switched it up he grew his salary exponentially.

As that Wikipedia article says, the continuous-time equation for exponential growth, x(t) = x(0) e^(kt), arises as the solution to the ODE x'(t) = kx, where k is the constant growth rate.
Similarly, in discrete-time, exponential growth follows the equation x_t = x_0 (1+r)^t, where r is the constant growth rate.
Been with the same employer for several years, jumping between web and native projects in all those years, across multiple clients.
Inflation was never a problem.
