How can share and share alike work when applied to income?

There is that saying share and share alike but how can that really work when income is he issue? If there were some way for the government to redistribute the wealth by way of taxes or some other non-socialist way wouldn’t the US eventually run out of the wealthy to pay that money in the long run? If people thought why break my neck to become rich when I will get a share of the pie off the work of others what incentive would there to be rich? And if people still strived to be rich would tax evasion skyrocket? If the rich thought he earnings they made or created was going to be divvied up with those who did not help create or put any effort in they might do whatever to hide as much of their actual earnings as possible. When it comes to income how can share and share alike truly work?
