The thing is that, your dream of the whole planet having a universal basic income system, is completely idealistic and rather impossible given the prerequisites that you are in. You can't force an evil force to be good for the sake of being good. There has to be something in return for them to make it happen. And something as major as everyone just receiving enough money to get by without putting in any work's going to be a little too much for the government.
So yeah no, the governments wouldn't have a plan for this. They'd rather watch the planet turn to ashes rather than actually make something happen. If it doesn't make them coins, it's not going to be in their brains. Better do something and get your ass off to work then
The government is like a farm where insects have attacked the farm and gradually eating up its produce and that is how people in the government behave they are the insects eating up the country and eating it, and they will change because they are already obsessed with wealth and power and you can not change them because it is currently out of the country, and in some countries, all they care about is to steal and squander money kept for projects, and the only plan I see the government having is for their interest and not for its people and the record of bad government is widening and it is becoming with remedy.
What can the government do? They basically don't have solutions. Whenever economic geniuses think of a solution to an existing problem on the ground, they create a new problem, because the systems followed by the government are corrupt systems that simply cannot solve any problem.
The situation may be worst in poor countries, but rich countries also have major problems that are worsening day by day, and the global economy is heading toward collapse.
There is no solution except to change these rotten minds that have controlled all governments for many years and replace them with younger ones that are able to understand the developments and needs of the times.
it is just as if the solution they are coming up with is a problem and after everything you see analysis making different speeches on the right thing to do and even with their analysis they still don't have a solution to it, take the housing sector, for example, its a problem that the government have been seeking for a solution for years and still can not beat the number of people homeless, the best anybody can do is to get their self to engage to be able to provide for their self, and rich countries to have their challenges because in a way the country is expanding and the economy collapses is every were just that some countries are still better, the key of getting better is now in our hands.
