I wish it were that simple... even if everyone tried to "collaborate" to produce the same product, there would still be some competition somewhere, at least for ideas. somehow the final products to be made need to be decided upon and the other won't be made. That also means, that somehow the people overseeing the final products have more power than the ones that were not chosen by whatever process is in place to make those decisions...
It really has not been proven, that there is a more effective organisational form for this competition better than capital allocation using markets with a lot of freedom.
For your case or "cross-generational" pensions where the young pay for the pensions of the old: That worked well while the baby boomers were working. This may go sour when the baby boomers retire and the numbers of their first and second generation of offspring decline... Even worse: if they have made the economy, tax and debt burden for those offspring so bad, they can barely buy their own home.
