I agree. It also makes me think of the knock on effect on self employed people like hairdressers, taxi drivers etc.
Well that's just daft!
So are people meant to spend money they cannot afford anymore, or on things they don't need, lest the people supplying the service(s) go under? 
Should people not quit smoking to keep to tobacco industry going?
Should people continue to go to the pub 3 times a week even though they can no longer afford to, to keep all the pubs in business?
Should people still use a taxi to get to work, even though they live only half a mile away, instead of 3 miles away, to keep the cabby in business?!
Should people keep going for meals out that they can barely afford (or don't need,) keep going for the meals out, to keep the restaurants afloat?
Your point is ludicrous.
For every person who stops or gives up something, someone else will start! The world won't stop turning because me and DH only have 10 takeaways a year now, instead of 26, or because I only buy 1 magazine a month instead of 3 or 4!
