History would have taught what labour governments are about though, even to the point that the IMF has to bail them out as they have no economic savvy what so ever. Playing Father Christmas might attract votes, but bankrupts the country.
It is indeed the young that generally vote for them as they think they will gain (the freebies). When they get older, they suddenly find out that they have to pay for those freebies from days gone by and get wiser and vote different.
I am not the biggest TM fan either, but with a choice between pain and ruination, the option should have been clear for anyone who thinks about the long term and not the short term handouts.
It is not for nothing that financial markets collapse if there is chance of a Labour win, and when going in Brexit now, no foreign company wants to deal with a government that will tax them to death and force a layer of red tape that will cripple them (nor having pay rates that are not competitive or a work force that can not be easily changed in size as once hired, impossible to fire).
Note that a previous Labour government caused the whole Islamic issue to explode, and the thought of another Labour government who would welcome them all in the UK by the looks of it, is quite frightening.
