''Musk might soon realise how he's been used to fulfil a stupid desire to cut costs ''
the desire wasn't to cut costs. Trumps desires, aside from limelight - are all based around revenge.
And the victims won't seem logical to others. In his head - he'll have targets - and for sane people who don't know how his head works - it will appear totally illogical.
Trump is a very sick puppy. A lifetime of non acceptance and recognition by almost all, makes almost all the enemy. And his supporters - are like birds of a feather in many ways.
