Umm.. the exact same people that grew them under communism, mercantilism, feudalism and non laissez faire capitalism. "The market" is a way to allocate 'capital': money, labor, and general stuff. It's not the only possible way. Further, an attack on laissez faire capitalism is not the same thing as an calling for the abolition of capitalism as a whole.
My point was that somebody MUST work if we all want to eat. There is no solution to the problem that does not force people to work for their survival.
Here's how to do basic income. Starting with 2010 GDP as a base, 50% of all GDP after that goes into a basic income fund that's distributed to everyone. It starts out small and eventually grows to a point where no one has less than a 1/2*N share. For example, let's say GDP/capita is $40000 in 2010. If it rises 2% to $40800, then $400 goes into the basic income fund.
If the result of the basic income is that people become lazy and don't work, the basic income falls or is phased out and we call the experiment a failure.
