Why are fewer English people going to their local pubs for a drink? Are they aware that many pubs are shutting down due to lack of customers?

You have to understand what the attraction of the English pub was in the first place.

You can get takeaway or even cook yourself a wider range of food of good quality

Back in the day (early 20th century and before) the English pub offered things you couldn’t get in a working-class home:

Why would a person who is educated and skillful still find it hard to get a better job?

Your home has more comfortable seating and a garden

You have 1001 sources of entertainment on TV and the Internet

In the mid to late 20th century they added food, without the inconvenience of cooking it or washing up.

Entertainment (pre TV and radio)

The pubs with the best chance of survival long-term recognize that they can’t just get away with the same 3 beers, ropey wine and pub-grub. Why pay more for something worse than you can get at home for less?
