Stop clobbering of the rich, warns Chris Grayling He also outlined measures which included the possibility of separate sectors, such as finance, IT or construction, being made to pay their own, higher, minimum wages. Asked when he would "bring back socialism," he replied: "That's what we are doing. It is about fighting the battle for economic equality, for social equality and for gender equality too. The Labour moves were criticised by business groups. The CBI and the Institute of Directors warned that the minimum wage plans would hit growth and increase the burden on business. John Cridland, the director general of the CBI, writes in The Sunday Telegraph's business section today that "growth must come first" and warns that if businesses are not allowed to grow, they cannot raise wages. In another policy announcement, Mr Miliband said that large firms would have to train a British apprentice for every worker that they bring from overseas. He said that the policy would create 125,000 new apprentices in five years. The endorsement of socialism by Mr Miliband suggests the party plans to raise taxes on the wealthiest, despite Rachel Reeves, the shadow chief secretary to the Treasury, saying on Saturday that single earners on £60,000 in south-east England were not "rich." However, the "privileged few" on salaries of more than £150,000 should be expected to contribute more, she indicated. The party has already called for the 50p rate of tax, which the Coalition cut to 45p, to be reintroduced for those earning more than £150,000 a year. Mr Grayling writes that protecting "wealth and job creators" from tax rises is a "red line issue" for the Conservatives in "any future government." He writes: "The politics of envy is back. What do Labour want to do? They want to penalise the wealth creators. Higher taxes for the rich. To pay for what Labour really wants - a bigger and bigger welfare state. On Saturday night, an assessment by the Conservatives suggested that Labour has already created a £27.5 billion "black hole" in unfunded promises. Mr Grayling criticises the Liberal Democrats for wanting higher taxes, using rhetoric which will be welcomed by Conservative grassroots who are concerned that the party is not doing enough to set itself apart from its junior partner. The Lib Dems announced at their party conference last week that they would target the well-off with more tax rises if they remained in government after the election. Danny Alexander, the Chief Secretary to the Treasury, said those who "have the most will continue to contribute the most." His party will campaign for a "mansion tax" on properties worth more than £2 million, while a leaked email suggested it is planning to raise taxes for people earning more than £50,000 a year. "One of the big themes of last week's conference was higher taxes," Mr Grayling writes. They want to penalise the wealth creators too. Both say it's a red line for any future government. Conservatives want to support wealth creators and job creators. Mr Grayling's defence of "wealth creators" is likely to set the tone for next week's Conservative Party conference and comes after a series of positive indicators for the economy, including falling unemployment and renewed confidence in growth. The ability of the private sector to create jobs has pleased ministers, as it had been claimed by Labour that it would be unable to deliver the number of new jobs needed to sustain a recovery. A Conservative attack on both Labour and the Lib Dems on the issue of tax reflects growing confidence in the party that it can fight for an outright election victory. A poll on Saturday night found that the Tories have an 18-point lead over Labour as the party most trusted on the economy. Ipsos MORI found 38 per cent of voters believed the Tories had the best policies on an issue that is set to dominate the 2015 election, with just 20 per cent supporting the economic alternatives proposed by Labour.
