I have long advocated for a basic income as half of a radical simplification of the taxation and benefits regime. In my version of the proposal, the basic income (popular with the left) would be mirrored by a flat tax (popular with the right).
Everyone would receive the basic income (B). Everyone would be subject to an income tax (r) on all of their income (I)where income is as defined as money that comes in (salary, dividends, capital gains, profits, inheritance, gambling, whatever).
There would be no other taxes (no sales tax, no property taxes, no payroll tax - and no deductions or credits) nor benefits (no child credits, no food stamps, no pensions, no unemployment benefit, no medicaid).
The tax code would be simplified to:
T = rI - B
There is something in this for everyone:
For libertarians, it drastically reduces the role of government and their ability to meddle with incentives.
For progressives, it drastically ameliorates poverty.
For conservatives, it eliminates disincentives for high income people.
(Not quite everyone - it will suck for Intuit, for the armies of people employed by the IRS and for the armies of tax advisors who do battle with them.)
To avoid hijacking more than I already have, I’ll restrict my comments to the basic income side of the ledger.
The biggest benefit is that it encourages people at the margins of poverty to find work. As others have said, the current system penalizes people on welfare who want to get off welfare. With Basic Income, any additional income you earn is gravy. Assuming, as I do, that most poor people would like to escape from poverty, basic income gives them the leg up that they need to become self-sufficient (welfare does not do that).
A common reaction, when I describe the proposal, is that the Basic Income would give money to people who have done nothing to deserve it. There are certainly truly lazy, worthless individuals who would take advantage of such a system but I expect that they are a fairly insignificant proportion.
Giving money to people who do not deserve it is certainly inefficient - but possibly less inefficient than all the alternatives. On the other hand, many classically lazy people will realize that, OK, they can get by on 12K a year or whatever, but life is so much more pleasant if you earn a little extra. They’ll learn the habit of working - a lesson denied to them by the perverse incentives of the welfare system. Suddenly, they’ll have an incentive to work.
There are some problems with basic income that I have not been able to resolve: what about disabled people who can’t work? Do they get extra money? What about the incompetents who fritter away their income? Do we intervene to make sure they can still get food if they fritter away their money on drugs?
Other problems are more straightforward:
Q. Should a married couple get two helpings of basic income or something less?
A. The People can decide depending on whether they think government should favour or penalize marriage. (my preference: government should be neutral on marriage)
Q. Should children get the full amount?
A. The People can decide to pro-rata the amount (or not) depending on whether they want to reward child-bearing.
The same kinds of concerns apply to illegal (or otherwise) immigrants and to prisoners. Although, withholding the basic income could be an effective punishment (and cheaper than prison).
Some non-obvious advantages: it eliminates the need for a minimum wage which would create employment at the low end. It would eliminate whole branches of the government dedicated to administering welfare.
In short, I think the idea of basic income is sound and coupling it with a flat tax makes it more palatable politically.
