@Believeitornot you are spectacularly missing the point of the part of my post you’ve quoted.
My personal experiences of living in the U.K. vs living in Germany is that there is a different attitude to money/spending/debt. Which I believe is a contributing factor to the difference in poverty levels.
The examples I listed were everyday things that I see here en masse which I didn’t see in the U.K. where people, in general, are more careful with money. It’s about an attitude and lifestyle difference.
I am categorically not saying that these few things I listed off the top of my head are the answer to the U.K.’s poverty issues, and I think you’re being slightly obtuse in implying that.
However, that said - why not grow your own if you can. Unless you absolutely have no choice to go into debt - don’t !
