The economic downturn calls for a boost in the income of those at the bottom of the pyramid. Lower income tax increases disposable income, therefore, it may encourage people to spend more but it also makes working more attractive. But it�s a bit �finger in the air� really as it depends on how and where the tax cuts are implemented and how the tax cuts are funded � by reduced Government expenditure elsewhere, e.g. government programmes, health, MOD, welfare etc.
For the short term it could work to benefit the economy, but long term the impact of those cut backs in government spending will affect public sector workers and contractors and their employees who rely on that type of work as their income. If disposable income goes up, the cost of living will naturally follow.
Perhaps their efforts would be better spent trying to reclaim the estimated �97 billion underpaid in tax each year by requiring billionaires living in the UK to pay the taxes that ordinary people already do, eliminate the tax perks enjoyed by private equity groups and hedge funds, then go after the �billions stashed in offshore tax havens, curb corporate stamp duty, transfer pricing games and much more.
If such money were recovered, it could be used to raise all tax-free allowances, reduce basic rates of income tax and increase pensions. But that would mean upsetting the rich and the corporate cats. It won�t happen.
