Mike said that cutting the 50p tax rate was completely unacceptable while unemployment soars across the UK - and Scottish youth unemployment hits record level.
"It is completely unacceptable for the government to cut tax for the rich few in society while a whole generation is consigned to mass unemployment because of crazy austerity economics", he said.
"Freezing the miminum wage for young people is unfair and will do nothing to address poverty or joblessness. Over 100,000 young Scots are now jobless - that's the highest figure for a generation. And that's why the STUC called for the demonstration."
