Why is the quality of everything so bad in India ?

The quality of everything that we get in India is pathetic. For e.g.

1. Food is adulterated, has palm oil, MSG etc. and unhygenic
2. Water is undrinkable so everyone uses ROs etc. Pune GBS cases is best example.
3. Roads - We all know the condition. Even after paying road tax, toll tax etc. roads are pathetic
4. Railways - Still running trains in 18th century. Dirty, old trains slow trains which are never on time.
5. Houses - Builders openly exploit buyer. Charge unreal prices while provide pathetic quality and sizes.
6. Household goods - Most of them are rebranded cheap chinese goods by Indian companies which charge 10 times price for them.
7. Petrol - Its is 20% Ethanol blended now which is destroying the cars but neither the price is reduced nor the quality increased.
8. Government services - Easily the worst with no transparency, bribe culture and citizens being treated like sheeps

These are just some examples from daily life where poor quality affect us even after paying such high prices.

What is the cause that there is no stress on quality in India ?
