>This is also a cultural issue. In large cities, people often don't feel as being part of the community and they don't take pride in their surroundings. They put rubbish everywhere, vandalise. There is little done to change that. They see neighbour has nice flowers in the garden? Instead of admiring, they will cut them off.

I don't think this aligns with the lived-experience of most Britons. The big cities are mostly litter-free areas, and people can have well tended gardens go unmolested by neighbours.
