As someone who thinks that on balance she did more good than harm, I will: Selling off critical national infrastructure built with tax payers money to private interests was a huge mistake - and morally wrong too. As bad was then continuing to subsidise the private companies with more tax payers money while the revenues went to private shareholders. Further to that transport networks, energy, water and others constitute strategic assets that should never be in the hands of private companies, imo. They are there to underpin the basic operation of the country and as such should not be privatised. That is not to say they could have been run far better and more effectively than they were before privatisation, but there the union problem rears it's head again.
