The way that Musk runs TESLA seems rationale to me personally.
Sure, republican could reduce the government subsidy. However under republican government, it is expected that the oil price would rise and that would be a big help to electric car companies.
The only way for Musk to be successful is to go mass production and increase volume. That requires huge investment upfront. It is amazing enough that MUSK could get together all the resources and investments to fund the infrastructure building for mass production. To me I think this is the only way that the company can be successful.
However I am open to second opinions and willing to hear if you do not think Musk is doing the right thing, what would you do if you were in his position?
