Socialism's results have ranged between the merely shabby and the truly catastrophic - poverty, strife, oppression and, on the killing fields of communism, the deaths this century of perhaps 100 million people. Against that doctrine was set a contrary, conservative belief in a law-governed liberty. It was this view which triumphed with the crumbling of the Berlin Wall. Since then, the Left has sought rehabilitation by distancing itself from its past.
If one generation is expected to carry an excessive burden on behalf of another, it will seek by every means to avoid it. It will either demand that past promises are broken, or it will not work, or it will not pay taxes, or the most talented people will leave. Socialist governments which have tried to tax 'till the pips squeak' have ample experience of that.
