Re: “Right attitude” varies (PM Mailbag Friday, 26 February 2016) – How do people get to be ‘billionaires’ in the first place? Do they massively overcharge for their products or, like the detestable Bill Gates, keep bringing out ‘upgrades’ that no one in their right mind wants? I don’t want their charity, and I would put a limit on personal wealth of £50,000,000. Anything over that would go back into the public coffers for governments to use as they see fit; like developing clean energy projects and driverless electric transport. If the rogue billionaire Donald Trump becomes president of the US, he’s going to ‘surgically’ remove the problem of North Korea, quite possibly leading to WW3.
