I never heard that nuclear power plant workers had a lower life expectancy or more than a very slight increase in cancer rates. And they’ve got a good salary in the US. And Japan is supposed to be so meticulous and up to date with all their engineering.
So why on earth would the yakuza have cornered the labor market? Maybe the atom bombs terrified the Japanese so that they really really don’t want to work at nuke plants - but if they’re that scared why have nuke plants at all? Or why not have the most fanatic schedule of inspections imaginable?
Because they are corrupt.
