I guess this practice is everywhere, even over here once a product is launched it would only take a few years maximum before its quality gradually decreases.
It can be very annoying when you no longer get the same quality of a product you are used to even at a higher price. !LUV
This is true for the most part I think. There are some smaller brands out there who still care about quality but you have to really do your homework because the larger mega corps have a tendency to buy these companies stealthily then gradually decrease the quality of the ingredients to increase profit margins.
