I disagree, The LibDems are advocating some pretty 'out there' policies, Road charging, immigration amnesties, local income tax, VAT on new build houses including low income housing and so on. He actually wants to tax the poorer sections of society more, not less.
He wants to cut working tax credit and child tax credit far more than the Conservatives, who just say people earning more than £50k do not need child tax credit. The policies do not advocate a fairer society, regardless of what Cleggs soundbites may say.
Economies rely on private businesses, not Governments. To support business is not a bad thing or an indication of stupidity as you claim.
