If the concern is that the money be spent, vouchers are unnecessary for aid directed to those in the bottom six or seven deciles of the income distribution.  Wealth and income have become so skewed that they have little choice but to spend all they get.  But most of the top 3% of income earners would rather see the universe implode into a new big bang rather than reverse the flow of wealth which has served to so enrich themselves.  We call reversal of that flow class warfare in the good 'ole USA and the fundies and the Scots-Irish descendants, often one and the same, see their troubles as God's Righteous Punishment for our wickedness.  

As the Dutch said while fighting the Spanish: "It is not necessary to have hope in order to persevere."
