A product is either superior to other products or not. Do not patronize an inferior product out of sheer nationalism or in the hope that your patronage will lead to its improvement. Because, it won't.

It is the producers' problem to come up with a superior product, not yours.

Besides, after all the past centuries, if a product is still not up to par, it is most probably due to the producers' mentality rather than to their amount of capital.
