Do the De Broglie postulates fit too into Occam's Razor ?
Definitely there are no doubts that Standard Model is deeply flawed and unrealistic. It's an excellent example of Occam's Razor principle violation.
Also the mainstream Dirac equation interpretation is not acceptable.
It's quite easy to find the electromagnetic origin of the inertial mass (i.e. Newton law F=ma) using the vector potential, but as far as I know nobody has proposed a pure electromagnetic origin of inertia using only E/B fields.
