The demand is the first step, a business can't make any money without demand.
Job's can be created (by the state for one example) to exploit that demand - the only thing that's required is the demand.
You also need to differentiate between A business & the current business.
If laws are put into place which causes businesses to go bust, new ones will crop up & take advantage of the gap left in the market.
I don't think the tax-payer should be forced to subsidise businesses which don't make enough money to pay the staff members decent wages.
Those businesses should go bust & more efficient/less greedy companies which can afford to pay reasonable wages will be able to exploit the gap in the market.
What you are supporting is corporate welfare, a system in which the tax-payers are forced to bump up wages which are below what's required to live on.
I agree with all of your post - but I am not in any way supporting corporate welfare
