When America had the great depression they built a railway to get out of it
That's called Keynesian economics, BrandNew. The US was not mired with huge public sector debt in the 1930's when the "New Deal" was announced. We however have huge - albeit reducing - public debt.
reopen the factorys, sort the mines out and unfuck all what thatcher did
The mines are closed and cannot realistically ever be re-opened for technical reasons. Even if they were, we are closing coal-fired power stations because they produce too much CO2 which allegedly will cause a potentially catastrophic increase in global warming. So that doesn't work.
As far as Margaret Thatcher is concerned amongst the many unpleasant but necessary things she did was reform trade union and liberalise employment laws to enable the economy to function properly in a way that was impossible in the 1970's. I'm old enough to remember the trade unions holding society to ransom over ridiculous wage demands resulting in power cuts; uncollected rubbish and unburied bodies. If you're aged under 45 you've probably never experienced any of those things.
When we're skint we're not spending like we used to and this has a knock on effect
See above. You can't spend what you haven't got. Credit is a temporary fix but capital and interest have to be repaid or eventually you become bankrupt (a bit like some Tin-pot republics and 1980's left-wing councils have done).
I don't believe nuclear weapons have any place in today's world as a deterrent. If we has a nuclear attack and struck back we'd probably be causing the end of this world
But if the other guy knows we've got the means to retaliate he's less likely to do so? That's why the Cold War never turned into a hot war and why unilaterally disarming in the face of hostility isn't very sensible.
The whole ironic joke of this is that we are fighting them with the same weapons we fucking sold them. We created this mess
Which weapons are those, BrandNew? Ak47's? No, they aren't made in the UK? IED's? Er, no. DSK anti-aircraft artillery? No - Russian again. We have not armed ISIS or indeed any militants in Iraq.
Why should a fire engine go and put out a fire in Starbucks when the amount of tax they have paid probably adds up to one fireman's salary
I think you'll find Starbucks owe somewhat more in corporation tax than the £30k or so a year a fireman earns.
Like I said, it's easy to bitch and whinge but you need to articulate a credible alternative - not these vague, woolly notions. Government's don't function like that and credible, electable parties can't either.
