To replace a social security system primarily financed by contributions and based on wage solidarity with a rent paid by the Government and financed by tax income seems a war machine against the welfare state. In addition, an income provided unconditionally to anybody can only be mediocre and cannot ensure the financial independence of the beneficiaries. These would be obliged to accept to work for whatever wage in order to round up their benefits. As a result, there would be a degradation of the labour market and a proliferation of badly paid jobs (source)
