There is the old saw that many of us have heard, which is, "what would you do if you knew you couldn't fail?", which I suspect is supposed to be an object lesson in breaking out of our fears of the unknown, of failure, and of not pushing the envelope further than we thought possible. The problem though with this sort of sham thinking, or exercise, is that there is no bravery, no courage, and no victory in performing or doing things which you cannot fail at, because there is no risk involved, no matter how you slice it. Additionally, in the real world: all decisions, even indecisions, have consequences, so that, especially in a country that congratulates itself unceasingly that we are the bastion of free enterprise, there is that certain knowledge that to achieve your goals, you must prepare, work hard, and must take calculated risks in order to accomplish things of real merit.
In regards to a government, especially a government that has gotten bigger, larger, more invasive, than ever before, this size and impact of government has dramatically changed the dynamics of business in America, and typically not for the better. There is in the scheme of things, typically no shame in failure, especially if lessons can be learnt from that failure as they so often are. The only real shame in failure is the type of failure that comes from ridiculously stupid activities, unrealism, lack of capital and proper pre-planning, an inability to adjust to objective facts, and so forth, to which those that are ill-prepared in one form or another, often receive their just desserts of failure.
Unfortunately, when the government has a budget of nearly $4 trillion dollars all sorts of nonsense can be backed by the full faith and credit of our sovereign government. Additionally, for political reasons as well as other assorted governmental policy excuses, there are programs created and are part of governmental policy, that signify whether implicitly or explicitly that the government will back certain companies and industries at the expense of other companies and industries, all in theory, for the betterment of the people. In actuality, of course, government guarantees to which the government determines where the people's monies should be allocated, actually disrupts the normal give and take of commerce and business activities within America and instead allows certain select representatives of the people to hand select who to back at the expense of those that are left behind.
This means in a nutshell, whenever your industry or your company is backed to the hilt by the government, that the economics of how your business is run, is entirely different, because when the power behind you, "guarantees" that they will make good on whatever silliness or stupidity that you create, all sorts of havoc will originate from this ill-advised policy. For instance, knowing that you cannot fail, fundamentally changes the incentives of a company, so that risk taking, especially risk taking that will benefit the most significant players at a given company, becomes incentivized, since the downside appears limited and/or even guaranteed, whereas the upside could put you and yours on easy street, forever.
In short, governmental guarantees of loans and businesses takes the risk away from private enterprise, and instead unfairly burdens the taxpayers to which they end up paying full freight to essentially subsidize the favored businesses of their governmental masters
