Many people purchase bottled drinking water via delivery service b/c they deem the quality of tap water unacceptable for consumption.
Many people invest in UPS units, backup generators, etc. b/c they deem the reliability of power from the grid unacceptable.
Imagine if the power grid had an additional 9 of reliability -- it would save hospitals tens of millions of dollars on redundant power backup systems, significantly reducing the cost of healthcare. From this vantage-point, the poor quality of grid power is subsidized by those who need life support systems... this seems horribly unfair.
