Like Amazon who exited China it is cautioned that Walmart my exit Flipkart if things remain unfavorable like they are today.
A big perception (some reality too) has been created that the small business is suffering most.
From consumer point of view It is good if he gets something at discounted price
From business point of view they need at least 20% to stay and grow business
But in this some points overlooked
Cost of running small/medium business has increased a lot mainly due to High Rent, Other establishment costs like electricity, Staff salary and stiff competition.
Then there are D Mart, Big Bazaar, Star Bazaar and many others who manipulate market and offer big discount effecting nearby small business.
There can not be any simple solution of this situation except Only Fittest survives.
Many business have undergone huge changes like Barber shops, Tailor Shop, Electronic Service center, Cloth store, Garment Business.
Due to Amazon consumers buy expansive items at affordable rates too.
So sooner or latter thing will change.
