In my humble opinion, you have been brainwashed from birth to believe right wing propaganda.
That cost for nuclear power came from the CSIRO, our world renowned science research body.
The coal fired generators were polluting, ugly monstrosities that stole good farmland and routinely killed people with their pollution. The CO2 they produce is killing the climate.
It’s not people telling it like it is. It's right wing media exaggerating a statistically small problem, knowing you didn't pay attention to that part of Maths at school.
