It was private sector economic growth that allowed for the infrastructure development of the 50s and 60s. If all that infrastructure investment was growing the economy, the 70s wouldn't have been a recession.
There is a tendency for those on the Left to think that all economic growth comes from government stimulus, whereas the Right believes that it comes from the private sector.
With all due respect, I think it might be a little more complicated.
Look at the consumer electronics boom that came from the technology developed by the Cold War Pentagon and Space programs. You will see a complicated partnership between the private sector and government. Look at the multiplier effect that came from this technology, and the profits it enabled . . . all of it heavily dependent on government lead investment.
(Government provides a
scale of investment that the private sector lacks; this is why business flocks to Washington for subsidies and favors. This is why business funds elections.
Son, capital craves the leverage of government.)
Look at the lobbying industry in general. The private sector invests billions to secure trillions in public subsidies.
Study the development of the computer and internet and you will see a dense network of relationships between the Pentagon and the private sector. It is a simplification to separate government and the private sector, not least because the private sector doesn't want the separation: indeed, they crave government money. (Please turn off talk radio son)
Study one of the my favorite Presidents, Dwight Eisenhower - specifically
the government funded and managed interstate system, which opened up the entire country to business, which gained a reliable, efficient, quick method for transporting goods and opening new markets. Again, if you study the interstate system (and if you pencil out all the avenues of profit it made possible) you will see - at its base - a complicated AND EFFECTIVE partnership
between the private sector and government. (The private sector denies the partnership so they can keep more of the resulting profits for themselves. And they invest some of their largess in Talk Radio for the purpose of convincing people like you to come to message boards and post sillyness)
Study the history of Boeing, specifically its relationship to the government. And then trace that history up to the commercialization of aviation, a source of massive profits. You will not be able to untangle the private sector from government in this instance either.
(This is why all businesses flock to Washington once they get big enough - because they want the financial leverage of big brother.)
Let's not even talk about the relationship between the Cold War Pentagon and private institutions like Stanford and MIT, where research and technology vital to the private sector was developed. Do you know any of this?
Son, please be careful with talk radio. The Hoover Dam, which is the reason why the modern industrial Southwest exists, was not made by private investments. No company was big enough, nor did they have the incentive to build something as large as the Hoover Dam (or the Interstate System, or the Space Program which created so much of the consumer electronics technology that fueled the Reagan boom).
Profit has always come primarily from a partnership between government and the private sector. In fact, these two poles are so intertwined that it makes no sense to speak of them as separate entities. The only people who think they are separate are naive voters who drink their party's Kool-aid.
Son, you trust government too much. By government I mean the Republican party which has created an infrastructure to funnel the profits of business into opinion management. Turn off talk radio. Turn off your computer. Turn off your TV. Go to a library. Read-up on the history of this country, specifically where the infrastructure of the modern industrial state comes from. You might discover that it's more complicated than you've been lead to believe. Don't do it for yourself - do it for the rest of us. Until you educate yourself, you will continue to vote for corrupt politicians who protect the status quo. We cannot afford your ignorance any longer (respectfully)
