Governments are slow, ineffective and non-responsive for the most part. You do not vote for most of the government. Governments, as institutions, will continue to expand their size, power and reach. I doubt you'll be able to shrink any government, other than by bypassing them using cryptos.
If you look at Venezuela, they have more than 50% of the country working for the government. A body that doesn't have to make a profit -- they can just print cash -- and they're not doing so well.
As long as money is controlled by a central authority, they'll continue to be able to manipulate and control/destroy economies.
The current state of affairs around the world, the current suffering is not by accident... it's by design. It's a very old trick. Create a problem and then offer a solution.
Government IS the problem. The Central Bankers ARE the problem. UBI would come from them, and therefore, it's naive to think it's intended to fix anything,
You can research Confessions of an Economic Hitman.
You can also research the effects of keeping the Federal Funds Rate at or near zero for as long as we've had it.
Then you can research the impact of all Central Bankers printing cash endlessly to keep up with the US.
And you can research the end of the Petrodollar, and the effects that will have.
Governments did all that. They are not there to help you. They answer to the Big Money who win them elections.
Finally, you may want to research #pizzagate and #pedoring to uncover just how much of our government is involved in molesting little children.
Is that the kind of people you want giving you UBI?
As certain as the Sun rises in the East, there will be people who cannot care for themselves... there are charities, and churches who take care of that, and do a much better job than a cold, black and white, government program with no accountability.
The facade is fixing to fall in the coming months. Over 1,000 sealed indictments have been sent out. You've already seen the sex scandals coming out of Hollywood, and starting to spill over into government... it's going to get messier.
I believe in people, like you and me, not in a faceless "government" who's too distant from the people, from the truth.
Lastly, the moment you turn your "power" to someone else, you lose it. If you say, "I can't fend for myself, and need big government to do it," will relinquish your personal responsibility, and lose your power.
We are plenty capable people. We just need to assume personal responsibility.
I'll have a read of the study you mention :)
