The money comes from taxes we have paid in. There are a lot of projects that can be paused to pay for this. Keeping people alive is a societal necessity and the correct thing to do. The cost of HS2 would pay for it with money left over
What is more important, shaving 30 minutes off a train journey to London or keeping people alive and well. As a Christian I can see that there is only one answer.
Keeping people alive is entirely dependent on allowing and encouraging everyone who is able to be productive. You seem to believe that your government has a bottomless bucket of money, that can be used to indefinitely sustain a majority of people forcibly kept idle. It doesn't work that way. It is not possible for it to work that way. Government cannot give anything to anyone that it hasn't taken from someone, and with too few people generating wealth, there is too little for government to take to sustain those not producing anything.
There is no other possible result from forcing a majority to remain idle and unproductive for any length of time, than that the economy will crash, people will be unable to obtain food, people will be unable to obtain other things that they need, and people will die as a result.
It is ignorant and insane to believe that you are saving lives by pursuing such an unworkable policy. This is a
“Great Leap Forward” level of insane, and it will unavoidably lead to similar consequences if it is not stopped.
