In fact the problems of supply that you mention are a demonstration of the failure of supply side economics. The whole theory is based on the idea that if you give fiscal incentives to the supply side, you will have more supply. But what we see in reality is that more fiscal benefits were provided and the industries are not responding, according to the examples you gave. Another example is the healthcare and Pharma industry: more incentives should result in more competition and lowered costs, but exactly the opposite is happening: consolidation and higher costs.
