Because they are better than the current opposition when it comes down to the economy and the economy trumps everything really.
Without a strong economic policy, job loses will occure,which effects people's lives more than anything really.
The current labour leaderships policies would destroy the economy, which in tern will reduce jobs, which means less tax revenue, which means even less money on infrastructure, health, education etc
It's alright saying we will fund this and fund that etc by taxing the rich and companies more but all that will do is stifle job creation and retention.
And that's not to say the Tories are good, they are horrible bastards.
I just wish for the sake of my family their was a competent and fair government for all spectrums, one that supported the poor and needy, funded health and education more, but by strong economic means by supporting small businesses more, creating better schemes for apprenticeship creation to give young people a chance, and bringing the economy back up.
Sadly labour isn't that right now, they would tank it.
