Yes the cost of strikes outweighs the rise............... but it is all, as a whole, totally unsustainable unless the UK changes something somehow or tries something new.
Debt at 99.5% of GDP, growth likely to remain low, interest on debt £80bn a year and rising, taxes already very high (apart from on the really wealthy) and every govt department wanting and needing more money................. how is this all in any way sustainable??
