If you're running a monopoly, and you're running 100% efficient, in what world would you be "making only enough money to survive"?
- you would accumulate savings certainly. However if you pay yourself a salary enough to live on and the rest of the money is always recycled back into the business to ensure that it runs at 100% efficiency what you have then is a fully self sustainable business that consumes almost completely all of the revenue that it generates in order to operate.
Basically if the operational expenses are almost exactly the revenues then there is almost nothing left after all of the expenses are paid. In that case what possible taxes can be applied to a business like that?
Any amount of taxes only would add to the cost of the end product/service and the result is a less than efficient system, where the consumers of the product/service are paying artificially more for getting the product/service.
In reality many businesses operate that way today already, of-course there are larger than average salaries going to the top executives but remove that and you have pretty much nothing left to remove, if you remove more then the business becomes less efficient/prices go up.
So to say that the businesses that will automate all of these jobs away will 'pay taxes' is nonsense, there is no money to pay any taxes. Any taxes added by the government will come out of the pockets of the consumers of the end product/service of the business.
In any case, the so called 'society' will not be able to extract money from businesses to pay for any type of so called 'basic income' or any form of welfare for people who don't work. The money will be extracted from everybody who is *not* a business, so it's quite simple: businesses actually generate all of the wealth and hire all of the people. Adding artificial cost to human labour increases the odds of automation / decreases the odds of new business formation / increases the odds of existing businesses leaving or failing. So the intelligent thing to do is to remove all artificial costs of running a business, removing the government taxes and regulations of business and labour, manipulation of money and interest rates and allow people to work out a natural fluid solution to these questions, not to try and hammer in the idea that those who work are going to be forced to pay for those who do not.
Those who work already provide everybody with all the goods and services that everybody needs, the contribution of any business to the society starts with the product/service the company produces with the added benefit of the person running the company being self reliant and not needing any form of help from anybody. Society should want to encourage people to start businesses and to do that it should remove the barriers to entry, reduce the costs of starting and running business, remove barriers, remove taxes, remove regulations.
The chips will still fall where they may but at least without government interference individuals will start businesses helping other individuals just like themselves. There *will* be separation of companies, some catering to the top tier of buyers, some to the middle and many (most) to the bottom tier. This should be happening now but it cannot because the companies in the top/middle tier prevent the ones at the bottom from competing and they are using the power of the State to destroy the competition by all means, including taxes, laws and money and interest rate manipulation.
