The late 70's were a bit like now. An economic model was falling apart. It required something different.
The Labour governments of the 40's, 50's and 60's oversaw the biggest growth rates of the last 200 years in this country. We've not got close to that since.
When you speak of growth, I assume you mean GDP. The post-war decades were a massive boom time (naturally) for all non-communist European states. You can't keep that up forever. In Germany we call those decades the Wirtschaftswunder (economic miracle). In power at the time were the conservative CDU (rather than the Labour-equivalent SPD).
Meaning, that fast growth would've happened under any relatively stable government as post-war decades were a very specific moment in time.
But even then, looking at GDP-growth of UK since post-war, I'm not seeing such a dramatic fall as you imply. I'm seeing ups and downs until Soviet Union broke up, then solid stability until the crash of 2008.
