I think that we tread far too cautiously around big business.
We always hear the cry that we will scare away huge, work-generating enterprises if we do the proper thing and charge them a reasonable proportion of their profits in taxes. But I think that the equation is fairly simple for the Google/Amazon/Starbucks of the world. In the UK, you might have an annual profit available of (let's say) 500m. We propose to take 200m of that away from you in tax, by stopping you avoiding UK corporation tax. Now, would you all like to abandon the UK in protest at our dreadful tax laws and forego the 300m you'll walk away with in your pocket ? In theory, the choice is between them staying in the UK and taking 300m profit out of it, or withdrawing from the market and taking nil instead.
If the Board took the decision to withdraw from the UK, just because the UK was a higher taxing environment than before, I would not be a happy shareholder. Daddy wants his 300m !
I know it's not quite that simple in the detail, but the principle holds broadly true.
Our politicians should grow a pair or two.
Could there be any greater conceit, than for someone to believe that the universe has to be simple enough for them to be able to understand it ?
