Jobs have to be profitable.
There's accounting profit - you make more than the cost of getting to your job.
There's economic profit - what alternative job opportunities you have given up by taking your current job.
@mongo can correct me if I am interpreting him wrong but I think what is being illustrated is:
If Model 3 is sold for $35,000 but cost $33,000 - Tesla makes $2,000 per car.
Even if SG&A is all accounted for in the $33,000 Tesla is still dead. They have debt payments that is continuing to accrue interest. 2000 profit on a per unit basis is not enough to keep the lights on.
They have to sell mixes of 3P, 3AWD with software to bring ASP up well beyond $35K.
I think Tesla needs an EPS of at least 0.01 in Q1 but I hope they pull off a surprise.
