Wow, I guess that was a revelation and something worth appreciating: the idea that if we just take a little bit of everyone's wealth and share it with the Commonwealth, then there can be a lot more wealth for all.
If sharing wealth leads to greater wealth, then why is it necessary to try to take wealth (by force)? Why don't people willingly give up their wealth so that they can make more? If it is possible to make more wealth by giving up some, why not let people choose whether or not they will share? If you theory holds true, then people who share will get richer and the people who don't share will get poorer and the problem…
If exercise leads to greater health, then why is it necessary to try to encourage people exercise? Why don't people willingly exercise so that they can be healthy?
