Looked at this thread many times and been thinking about it.
What do you mean by 'economise'? I am very happy to put back in question products and processes to use them better and more efficiently. Happy to look at holidays, family and friends- and re-assess if we can continue to entertain each other, have fun, but again, possible more 'efficiently'. Same for clothes, petrol, heating, hot water, etc, etc. Nothing wrong with looking at how we do things and re-assess, surely?
I used to jump in the car to go and buy one thing I'd forgotten- now I make sure I check the list, and if something is missing, tough, it will wait till next weekly shop, petrol is too expensive.
I now wash things which are not dirty, but just need refreshing, on a shorter, colder wash, and make sure machine is full. Etc, etc, - lots of small things, which, all added up, here, but mainly on the national/worl scale, can actually make a difference.
Economising on goods, processes, etc, but not on the actual results.
