I generally don't trust the government with the money because there are too many ways to give money to their friends. Even if it trickles down to us, it's probably diluted by then and the people with power or their friends have taken their part of the money.
The trickle down only goes so far, as most is taken at the top. And then, that trickle ends up going back to the top as we spend it at the corporations anyway. And because they always want more, we will continually have our own needs crushed - "live with less"
