Corporate tax windfalls are not what drive job creation. Demand is what drives job creation. Cutting the corporate tax rate in an environment where we need to reduce our deficit and address the national debt is about the worst idea imaginable. Corporate profits have consistently hit record highs each quarter for the last five to six years, so it's not as if corporations are in need of tax relief. Also, tax rates are not what drive price. A combination of supply and demand is what drives price. Corporate tax rates are fine where the are. Over 12 million private sector jobs were created during the Obama era under those tax rates.
If you want a tax policy that will stimulate the economy and create more jobs, cut taxes for the bottom personal income brackets and offset that by raising taxes on the higher income brackets. This is a no brainer, though it seems to escape the republican electorate. Tax cuts for the lower income brackets would provide a boost to aggregate demand, which would lead businesses to hire more employees to meet that demand.
What was the demand for small computers before venture capitalists using new money from Reagan's deregulation and tax cuts provided capital for companies like Apple, Microsoft, etc.? There was none, but the "windfall's from Reagan policies allowed investors to take risks on new investments that eventually drove the prosperity of the 1990's. No amount of middle class tax cuts intended to increase demand could have done this.
There was certainly demand for data processing, and more efficient means of consuming, storing, and sharing data back in the 80's. Personal computers were a vehicle to meet that demand. This is true independent of any regressive tax cuts.
Put another way, personal computers - much less regressive tax cuts - didn't invent the demand for data processing any more than the automobile invented the demand for transportation. You're mistaking technological innovation of an already existing, demanded process with the creation of an entirely new, not-previously-demanded process.
If you want to give the Reagan tax cuts credit for something that they actually created, look no further than our national debt. The trend of ballooning deficit spending and national debt begins in the 80s with Reagan's tax cuts. One could also make the argument that those tax cuts play a role in the skewed distribution of wealth and income that has taken hold over the last several decades as well.
There was no demand for personal computers because hardly anyone knew abou them and major companies like IBM and Polaroid who could have produced them didn't because they understood there was no demand for them. Companies like Apple and Microsoft were producing hardware and software for a small market for tech enthusiasts until financing from venture capitalists eager to invest the money they had made from the deregulation of financial institutions and the break up of stagnant corporations allowed these start ups to produce products that finally did gain the notice of both businesses and individuals. Because of this new source of financing these start ups were able to create products that then created their own demand and that is what fueled the economy of the 1990's. Without the bustling economy Reagan created with tax cuts and deregulation, the financing simply wouldn't have been there to launch these new companies.
You have an uncanny ability of missing the point, even though I clearly spelled it out for you. What do personal computers do? They allow us to store, share, process, and consume data. That said, people have been storing, sharing, processing, and consuming data well before the personal computer. And there has always been a demand for more efficient means of storing, sharing, processing, and consuming data. The personal computer met that demand.
Just as there was demand for more efficient means of transportation before the automobile came along, there was also demand for more efficient means of data processing before the PC came along. This is the point, and it is also the fallacy in your line of reasoning.
Whether or not Reagan ever cut taxes is of no consequence to the birth of the personal computer. The personal computer would have came about regardless
because it was a tool that met the demand of more efficient means of data processing. One more time: the demand for efficient means of processing predates the birth of the personal computer.
