Where does the revenue come from?
This article focuses on the US, but delves into that question:
https://www.vox.com/policy-and-politics/2017/5/30/15712160/basic-income-oecd-aei-replace-welfare-stateConservative and libertarian proponents tend to want to pay for it by eliminating the entire welfare state, including health programs like Medicare and Medicaid and social insurance programs such as Social Security. More cautious center-left or moderate libertarian proponents — who are loath to cut those aspects of the safety net, endanger people’s retirements, and let uninsured sick people die in the streets — tend to only propose funding through eliminating means-tested programs like food stamps and the earned income tax credit, as well as tax benefits such as the health care exclusion and mortgage interest deduction. The most ambitious lefty proponents want to finance the program entirely through new tax revenue.
A Canadian version of a guaranteed income would probably at the very least replace things like UI benefits, welfare, old age security, GST credit, personal income tax exemption and some other number of tax credits, and maybe more. It would replace the many ways we already distribute a lot of cash to many people with a simpler system, and would probably also allow the government to cut a lot of bureaucracy and inefficiency.
The article I linked above refers to some research into how revenue-neutral guaranteed income is playing out in 4 countries. There are winners and losers. The elderly tend to lose the most under such a system.
The article also looks at research by the (decidedly right-wing) American Enterprise Institute on a guaranteed income achieved by replacing almost every US social benefit with guaranteed income.
Four researchers at the American Enterprise Institute — Matthew Jensen, William Ensor, Anderson Frailey, and Amy Xu — used three open source models of American tax and benefit policy to calculate the effects of a UBI funded by repealing "most welfare and transfer programs, including Social Security and Medicare," and "most base-narrowing features of the individual income tax system." They throw everything into the pot: Medicare, Social Security, veterans benefits, the standard deduction, every itemized deduction (including mortgage interest). Basically the only major program not repealed is the employer-paid health care exclusion, and that’s just because there wasn’t data available to model the change.
Getting rid of all those programs would finance a UBI of $13,788 for adults and $6,894 for children. So a family of four would get a whopping $41,364. Then again, if they received health insurance through Medicaid or Obamacare subsidies, they’d lose that.
They found that once again the elderly are the big losers.
The number they came up with-- $13,700 per adult and $6800 per child-- is pretty staggering. As far as I can tell this figure was arrived at by taking the expenditures currently directed into almost every kind social benefit and instead redistributing that money as equal payments to every American. That really puts into perspective the vast sums of money already involved.
