Is it so out of the ordinary that a government tries to help people save money or what's the question? Sounds like you've only had the American experience in life unfortunately.
If something actually saves money then it doesn't require a subsidy because people would be doing it regardless.
Meanwhile the government doesn't have any of its own money, so it can't really give you something that was yours to begin with, all it can do is take it from you and then give it back with strings attached. How is that helping you? Instead of subsidizing something you can make up your own mind about whether you want, they should just lower your taxes by the amount of the subsidy and let you use your money for that or something else at your choice.
