The trouble this brand of Labour has is that it has no ability to weigh up consequences. The Tories under Major opposed a minimum wage because they said it would damage employment. They were proved wrong in principle by Blair, but only because he took a cautious view of benefit v risk and set the rates accordingly. The Tories adopted that approach to the minimum wage in later governments.
Similarly, Blair didn’t repeal any employment and union legislation of any consequence. He could see the risks.
But Starmer & co aren’t grown up enough or have enough spine to face down the studenty left of the party. So we’re getting massive burdens on businesses generally, but on employment costs in particular. Add in Miliband’s crazy energy costs, driven by his lack of ability to see a balance between carbon reduction and industrial necessity (another juvenile left policy), and you get rising unemployment and business abandonment of the UK. It will get worse.
