All I would go on is my experience :-
In the 70's - I remember the 3 day week , the miners strikes, secondary picketing and the council bin strikes with rubbish piling up. I also remember Thatcher and the divisiveness it caused , I also remember the 80's (leaving the bad music to one side) , I remember an economy on the up - on the whole, I also remember the riots. I worked for the council and then got a job in the private sector
In the 90's - I remember a bit of a recession in the early 90's - it didnt affect me - as I had a secure job. Mid 90's I setup my own company and was then responsible for my own destiny, finding customers, getting paid, paying a mortgage, travelling wherever to get work etc.
I remember Blair getting voted in (glad about that as the Tory Govt of the time was split down the middle). Tony Blair was good for me - with massive borrowing and spending by Labour - there was continuous work - some public some private sector. I voted against Blair in 2003 - because of Iraq and the subsequent total disaster it caused directly up to ISIS now.
Labour seemed to be going the same way as the previous Tory Govt of Major - split. Then we all discovered Gordon Browns trick - the massive spending was built on sand and PFI. Blair "go and get me immigrants from anywhere and let them all in", then we had him wanting to join the Euro (thank feck for Brown on this one). Tuition fees and a seemingly megalomaniac in charge and an economic plan which seemed to based on tax and spend (again) - it doesnt work in the long run.
I liked to Tory / Coalition idea - although they were always going to be completely hamstrung by the complete disaster left to them by the previous Labour Govt (not entirely their own fault - but they certainly didnt help) The Libs idea of 12k tax threshold compared to what it used to be - was great for kids on the step ladder of employment.
Clegg learned an important lesson early doors - he promised to get rid of tuition fees - yet when he had the power to do it - he admitted he couldnt do it - funny how the reality of power makes the opposition BS disappear.
Skip forward to today - your choice is vote for a man who has never held office, never been on the Govt or Opposition front bench and never run a dept etc OR vote for someone who was Home Secretary for a record 6 years - and didnt get sacked.
No matter what the political parties tell you - the people will have 2 questions when they vote - is the person trustworthy, do you think they can do the job. If you can get past those 2 barriers - then people will trust what you say - and you can talk about all the other stuff.
If you dont have their trust and dont appear to be competent in the job - then you can talk till the cows come home - people wont vote for you.
