Well, I don't think a specific role can destroy your voice. What can destroy your voice is when you. . . make an error. Everybody can make an error. But then you need to realize what is your way.
If one generation is expected to carry an excessive burden on behalf of another, it will seek by every means to avoid it. It will either demand that past promises are broken, or it will not work, or it will not pay taxes, or the most talented people will leave. Socialist governments which have tried to tax 'till the pips squeak' have ample experience of that.
