If you want to reduce government spending, go to the head of each department and offer them a bonus of 5 percent of every dollar cut from the budget. Watch how fast cost get cut.
You have conflated "government waste" with "government spending". I am sure when Trump has replaced every head of department with his cronies, they will be completely amenable to this corrupt idea.
This would work well if you were doing the cutting.... However, bureaucrats have no sense about what has value and what doesn't. They don't invest themselves into their work, they simply do the least work to get a project out of their way so they can go for a longer smoke break.
Only the poorest, elderly on pension credit and sick and disabled get cold weather payments now - and they tightened that to a criteria that rarely happens.
