That's ridiculous.
Tax cuts will pretty much ensure that almost none of that money gets to Blackwater. Sure if someone wants to send them a private donation they could, but really I don't think anyone will be doing that.
Tax cuts will however, realistically increase the amount of funds going to charities that serve the needy, like the Red Cross for example. I'm sure some of the money would even go to groups like Planned Racial Unparenthood.
If you had any concern for people's choices you would champion tax cuts as they allow people to make choices.
Your real objection to tax cuts is that they undue the unbelievably stupid plan of taking virtually all the taxes from the 5 percenters and having the other 95% of the population become dependent on government for it's basic needs. This is the kind of dependency that promotes socialism. It's a very feel-good scenario for those who are stuck in a class war.
Nevermind that good socialist countries have a higher disparity between rich and poor than the US does and bad socialist countries, like North Korea, just make everyone equally poor. Or that at best socialistic leaning countries, like France, have the same disparity between rich and poor as the U.S. We don't need to worry about those kinds of facts because equalizing the wealth distribution is not the intent of the architects of socialism.
The real intent of the architects of socialism is to grab all the money and power for themselves just like that is the real intent of many other people who manipulate the masses. All countries in the world have an elite group that makes the rules. No government in the world has eliminated this. The only difference is that in the US everyone is supposed to have an equal chance to live the good life as long as they use the skills their creator gave them.
