Public services are controlled by government, which is held as an necessary institution, and by definition can always exist in some form (i.e. if they run out of money, they raise taxes, etc). They have no obligation to help anyone other than for the "trust" that people have in them. In a democracy, anyone can get elected and takeover, but I think you are intelligent enough to know that this never happens.
Private enterprise, on the other hand, is dictated by the consumers and share-holders. If they pull out, the business will fail. Private enterprise have everything resting on the happiness of their consumers. They do have an obligation to help people, as if they do not, they will not have enough consumers around to be a successful business anymore.
The only conceivable problem with this system is through government interference. Companies that fail their consumers are bailed out by governments, rather than follow the natural death they should rightly get. Take out the safety net that governments impose on business, reduce the amount of regulation of business by the governments (i.e get the government as far out of the picture as possible) and business will be where it should be, in a position of trust because without consumers, it will fail.
