| You parent's argument is poorly stated if the desire is to appeal to conservatives. Indeed, many people will object for the reason you stated. There are a few premises that must be established to make a case for BI. 1. We are approaching a post-scarcity economy. 2. In a post-scarcity economy, many people will lose the ability to support themselves\their families, as whole industries are automated. 3. In the case of massive unemployment, consumption will drop dramatically. 4. Drastic drops in consumption will devastate the economy. This will be bad for everyone. Less wealth, less progress, less investment. 5. Therefore, to maintain economic growth/stability in a post-scarcity economy, we should provide a basic income. That's the best argument I can formulate. It really has nothing to do with having fun and not being forced to do menial work. Those are fringe benefits. |
As a parallel, consider immigration. From an economic point of view, open borders make a lot of sense because the supply of labor can easily adjust to the demand, so I've wondered for a long time why there shouldn't be free movement of labor as well as capital. Indeed, many people agree with this; I can't imagine you'd find anyone in the US that wanted to adopt China's houkou system, and require people from one state to get a work permit before moving to or taking a job in another state. Given the demographic situation in the US with waves of baby boomers retiring but also living longer the resultant worsening retiree:worker ratio, immigration also makes a great deal of sense as a way to keep a lid on payroll taxes and so forth, and this is coincidentally the last opportunity the US is likely to have to exploit a nearby foreign labor surplus just when it needs one (due to falling overseas birthrates and wage equalization eroding the US demand-side advantages).
Pretty much every economist agrees that more immigration with fewer restrictions would be a good thing for the US. But obviously a sizable contingent of the population just cannot stand that idea and any time such proposals are made in DC the objectors melt the congressional switchboard as quickly as possible to express their displeasure.
So I've given up hope that proposals for a basic income would succeed on the grounds of rationality alone.
