Is this for English or just general interest? Usually i'd agree with you so i'm taking some what of a devil advocates/awkward position towards myself here but i'll try.
Also just want to make it real clear that i'm not an economics student and i could be hugely wrong.
1. By supporting these large companies, thousands of jobs are saved which is intrinsic for the maintenance of a financially stable economy.
It really does depend though. If the jobs generate $20,000,000 a year for the economy or they pay $20,000,000 a year in salaries, is it really worth it if they want a stimulus package of $200,000,000 ? It seems like it's really not worth it paying all this money to save jobs, it'd be cheaper just to let them go on welfare. Definitely must draw a line somewhere, even the most hardcore person willing to handout money will deny extortionate demands. Take the recent case of SPC, they're owned by Coca Cola Amatail (the coca cola company actually just produces syrup, its shipped around the world to be made up with water and bottled by companies like this local Australian bottler). They're a very rich company. They definitely could have afforded to put money into it anyway.
Take another case, you say its good to save thousands of jobs, it probably is. Consider this though - hundreds of small takeaway stores across the country probably fold every year. This would probably come close to hundreds or thousands of jobs
in the aggregate. I don't see much enthusiasm for bailing out the local fish and chip shop. Obviously, its a little different considering the capital investment needed (it's cheaper to buy fish and chip shop equipment than it is for a big plant).
Capitalism is all about creative destruction. Whilst i'm fairly towards the left on the political spectrum, i have a degree of faith in capitalism and the market (a managed sort of kind anyway). There is a reason we don't have many blacksmiths or carriage drivers anymore, we simply don't need them. Their existence didn't match the needs and wants of society or the economy. They lost their jobs but new jobs were created in their wake as well. A degree of failure about things ought to be accepted in a capitalistic society like ours.
2. It is perceived that by bailing out businesses, heavier taxes will be levied in order to compensate for the assistance provided to the businesses. This is actually beneficial for the economy. If businesses are not bailed out, the government would have to provide financial welfare for employees who lost their jobs. This will not only impose heavier taxes compared to the tax rate in supporting these businesses but will also last longer. Therefore, by bailing out large companies, not only are we preserving thousands of jobs but also saving our own pocket money.
Really depends, see above. There's also more complex economic factors at play here as well. If we're bailing out a company that produces something no one wants, that's actually a rather large problem under economic theory. Take something like Christmas. Economists hate Christmas because it's what is termed a "deadweight loss". There's a difference between what people pay for the gifts they give and for what the people receiving them would have paid for them. I might buy you a Justin Bieber album for $30 but if you never wanted it or would use it, we've basically just burnt $30 in an extremely inefficient way. In theory, the market should perfectly reflect peoples wants and needs and should perfectly allocate them as such, economics is also all about rationing out the scarce resources we have (i.e. money) for the most benefit or gain.
Take Ford for instance, they were simply making cars most people just didn't want to buy. If i start a business selling snot flavoured marshmallows and they don't sell very well, i don't think i should be bailed out, that business should just fail, its the forces of the market sending the information its just not a product or service people want and shouldn't exist as we move towards a more optimal/representative market. Toyota was quite different as they were making cars people actually liked, i believe one of their cars was the best or close to the best selling in Australia.
There's also the question of future bailouts. If we give one now, what if they want another and another? Shouldn't the business be sustainable on its own rather than relying on constant bailouts? It all really depends.
3. All businesses WILL eventually collapse- it is a normal process. For example, just over a month ago, Apple's ipod business collapsed and the revenue plummeted by 55%.
Does this really mean that we should abandon this internationally diverse company? If we are to stop the government from bailing out large companies, we are regressing our growth as a nation- this is unethical and is not a healthy approach to dealing with downfalls faced by companies.
As above, sometimes we should just let businesses fail, indeed, supporting unsustainable industries ironically enough might be regressing our growth as an economy (imagine if we still supported horse and cart drivers or door to door milkmen). All things will eventually collapse thats true but i mean the Earth will be engulfed by the sun some day too. It's more about the time scale, we have some very old companies around. HSBC was handling British opium profits in Shanghai during the Chinese Opium Wars, thats how old it is (HSBC standing for Hong Kong Shanghai Bank). Arguably, we should only let the best and strongest businesses survive unless theres some other kind of social aspect to it.
