An example why socialism always fails

A chap on the YouTube was telling a tale how some people are not getting the £400 fuel thing in the UK this month because they live in a bed sit. It reminds me of one reason socialism always fails. I give this as an example. You have three children and three chocolate bars. How do you hand them out. Most will say one each. Then you point out one child is fat and the chocolate will kill him. The next has an allergy and will die. The third is starving and needs all three bars to live. Now some will still believe each child should get a bar regardless. Others will say you should ask them questions and so on. So if you take the second option it means you do not have equality. Plus now you have to spend a fortune on doctors and so on to interview and all the paperwork. Just to hand out chocolate to three children could mean years of paperwork. Expense of giving people jobs to do this. Now imagine this is a population of millions. You can see how socialism fails with ease.
