This is what a universal basic income or citizen's dividend is for. Consumers are the big movers in economy, and producers are the big makers; a portion of all income (individual and corporate) is taken and divided up among everyone (for some definition of "everyone"), stabilizing the bottom.
Imagine if all the homeless and unemployed had a fixed amount of income. Maybe $500-$600/mo. At $1.33/sqft (significantly more than I last rented), a livable microunit housing for a single individual would leave just barely enough for food, utilities, clothing, etc. Just barely. I think I have $50 of leeway in there at 17% of corporate and individual income (eliminating about half of taxes, including OASDI payroll tax, and applying a 17% flat to replace it). Right now, they have nothing, so can't buy anything; in this scenario, they have just enough to buy what they need to live.
This hypothetical creates an enormous market: if you fall to the bottom and lose everything, you still have the shirt on your back, enough money for a new shirt, and enough to rent a sardine can to live in (224sqft microunit; I may be able to get fancy without appreciably increasing costs, too...). Businesses can profit off this, while the mental and physical health problems of being homeless and hungry--starvation, unsanitary conditions, etc.--are lifted off the back of society.
On top of that, producers who fully automate are collecting profits. Automation reduces labor: it costs less to maintain a robot because it takes a collective 10,000 man-hours to produce a robot and 1,000 man-hours per year to fuel and maintain it (including mining fuel, refining fuel, shipping fuel, generating power, transmitting power, maintaining the power infrastructure, mining all the steel for the robot parts, refining steel, shaping steel, and sending maintenance people), but the robot does 50,000 man-hours of work in 10 years. 20,000 is less than 50,000, so that's 40% as many employment hours--40% as many jobs, if you will--for the same useful production.
This labor reduction by efficiency improvements includes far more than automation; for example, Toyota saved 45 seconds from a 65-second process building seats by using a shorter hose (raises the steam temperature) and installing the bolts in a different order (easier, faster access by the tech, who installs bolts and then steams the seats to drive out volatile manufacture chemicals). Many such optimizations allow the same humans to use the same tools to build the same things, but in 80% of the time overall, or 60%, or 40%; thus you only need half as many humans to build as many things in as much time.
The reduction of laborers and the increase in productive output means goods can come cheaper, but consumers are poorer. Fewer consumers exist. A citizen's dividend doesn't free us from work; it leaves us poor, but alive. It frees us from the terrible economic crash that comes when new management styles and processes. We will always find new use for laborers; but this comes after we put laborers out of jobs for a good while, and in the process destroy the labor force. Providing some return to the consumers for being consumes is, thus, advantageous to businesses: it provides them target markets to invest in, avoiding the economic problems of making higher-end goods for the working class which has just become the unemployed, and suddenly not having anyone to sell anything to.
A universal basic income, or a Citizen's Dividend in particular, is the solution to this conundrum. Universal vocational education--that is, college education--touted as a solution, is an exacerbating problem: laborers pay higher taxes or take on enormous debt to flood the market with cheap, skilled labor, giving employers the advantage of lower salaries as unemployment for a skilled labor class increases. Welfare, as a qualified service, takes on more operating cost as more people collect; while a universal income always pays at 100%, and is thus immune to the fluctuations of economy. To survive the economic dead zone between paradigm upgrades and new labor demand, we must invest in the maintenance of the labor force; and the best way to do so is to make them a profit source.
Someone needs to work; it turns out to be very few people, mostly those maintaining the robots. Labor is a resource, however: we suddenly have piles of cheap laborers who can build great big things for us, until we excess their new jobs by robots.
