For example, if we look at food, it's a competitive industry and prices tend to only rise when costs (labor, food supply, rent) increase. I don't see why this will change under basic income. People aren't going to want to start spending $20 at McDonald's just b/c they can afford to do so and if Carl's Jr can undercut McDonald's at $15 w/o taking a loss, they will.
I can see housing costs increasing. Everyone wants to live in the same areas, so the supply of good housing is constrained. This is reflected in housing increasing in proportion of a person's income over the last couple of decades while food and clothes have fallen. But I also believe alternatives will start appearing to meet the demand for basic income level housing. It won't be as nice, but at least people can have a roof over their head. As an example, dormitory style living or elderly care facilities.
Lastly, what are the alternatives? If you agree that the problem is that automation is going to make a lot of ppl unemployed while concentrating wealth to the few, what other solutions exist besides wealth redistribution? If we have to redistribute wealth, how else would we do it?
However, the point is that through automation we're creating more work and from who we're taking is the robots. If there are no new automation or robots to take from, then it is most likely that we're going to take from middle class, either directly or indirectly.
If you wanted a more reliable way to ensure UBI would remain effective, one way would be to treat it as a separate currency that could only be used for the necessities of life. Moves could then be taken to limit profits made on these goods without distorting prices in the rest of the economy. Could also couple this with government support to encourage automation and other savings in these industries. I'd argue both of these changes in combination can result in a UBI system that is protected against price hikes.
I understand that one may argue that they didn't get the opportunity. But from macro indicators to flagship cases, what we see is that while market brought us a wealth of new products, they are slow to solve acute problems, especially when these problems are hard to explain to the population.
This is why we need land value tax.
In K-12 education in Europe, lowest-performing students are given a lot of attention (with "special" classes etc), low-performing get the bulk, and little attention is generally given to high performers. The effort distribution is roughly normal, biased toward lower-end because of people with disabilities.
Goal seems to be to bring people to a reasonable average, but not above it. Education effort seems logical (the bell curve). Inmate "subsidy" does not seem as logical - perhaps a more bell-shaped subsidy distribution would increase the average/mean and also reduce recidivism (if in context of criminal law).
A reasonable imementation of the current argument is to gradually "normalize" the subsidy distribution into bell shape, which will move the "target average" threshold higher along the way.
Generally "normalizing" subsidies along the range of any metric theoretically sounds right. Sadly, given that value of any one person's life (and possible accomplishments) is not defined (=infinite) science cannot provide a solution. F.e. there is more benefit to aociety to help people with minor disabities, then with major ones, but people feel "inhuman" about supporting such statements and decisions this entails. This will become harder still when AI will need to choose allocation of effort to support/save lives.
