The expansion of MARTA and the light rail system via a sales tax is the great destroyer of wealth. Any system which cannot produce a benefit that is greater than its cost is not an asset, but a liability.
If a public transportation system is to be funded, then let it be funded by fare, not by a sales tax. Of course, it cannot be funded by fare because the cost of doing so would cause the fare price to increase such that the consumer would be confronted with a fare that is greater than the benefit of the service provided. Therefore, since the service is not self-sustaining (i.e. the costs are greater than the benefit), the cost must be subsidized by (looted from) parts of the economy that are capable of producing wealth.
The ability for a system to survive that destroys more wealth than it creates is in direct conflict with free market principles and market-driven demand. Such a system could not survive in a free market and therefore can only be achieved in the economic petri dish of a command (government-driven) economy.
Any system that consumes more wealth than it creates is economically evil and should be stopped.
