The reason for this is that until a couple of years ago there were no real restrictions on material quality use by the government. Fire hazard materials were available and much cheaper than the approved materials.Also as no house insurance is compulsary, no checks by insurance companies for quality. Now they are finally becoming aware of this and are at the start of implementing quality. Also remember the motto of construction companies is to make money. How do they do this? By providing/installing inferior quality. Who is there to check what they do?
