A lot of people seem to have a very strange conception of how businesses work - especially ones that rely on investors. These companies should sell at low profit and run as charities - if that is how we expect businesses to operate than Pakistan isn't getting any investments any time soon.
Mehran went out not because the company grew a conscience and decided people deserved better - rather because competition drove them to make that decision. That is exactly how it works in the west and every where. Cost-benefit analysis is used for decision making not heart and soul most of the decisions profit oriented businesses make.
With regards to increasing enforcing a better standard for products and such, the government has to do it part to ensure that by appropriate legislation and enforcement. However, all of that has to be done whilst keeping the realities of businesses in mind as well - a business is not meant to operate at a loss or a minute profit, rather investors have ROIs and other such measures that they used to decide whether a venture is worth investing in or not.
Last, every time some product is made more expensive or such there are people who come in and say it's all a luxury and screw anyone who partakes in that. Everything they aren't personally used to or affected by, is either disregarded as being useless or a unnecessary. Yes people have to make sacrifices to their living standards for the 'greater good' but that doesn't mean you have to demean the cost of it all for them. It is easy to say that person who sends their child to an expensive school should take him/her out and send them to a less costly one and 'suck it up' but that ignores the reality of the human condition and of living in societies.
It is indeed difficult, socially and otherwise, for people to reduce their standard of living. It is a natural desire for people to want to provide the best for their families and strive to improve their lot in life. That is what motivates people to work hard and increase economic activity. You cannot blame people for wanting it.
Most importantly, it isn't necessarily wrong to ask people to sacrifice some for the benefit of the whole but it should be viewed as a sacrifice. Belittling and demeaning the struggles of people does not help make it easy for them.
It's the same as 'there are kids starving in Africa' can't be used to belittle the feelings and problems of all the other people in the world. It's good to have perspective, but it works both ways. Life is a lot more complicated.
I understand that much of it has to be done and I hope and pray that Allah improves our economic situation soon and people can see an improvement in their lives.
