Most businesses fail. Hell, most Google products have failed. As such, overall private spending is woefully inefficient (despite a few big successes), and government spending is relatively very efficient.
Governments have the ability to tax in order to fund spending.
Businesses have to fund their spending out of either their revenues or their debt/equity funding. Is it any wonder that businesses fail more often than governments?
If the measure of government efficiency is return on the tax dollar, then by the same yardstick the benefits generated by most businesses are infinitely efficient.
- first, government spending is highly scrutinised, by the convention that people expect every tax dollar to be spent in a way that they deem worthy;
- whereas, most private businesses are not scrutinised in any sort of comparable way (often not even when they are spending tax dollars - which they can, directly and indirectly).
