Even if you suppose you can raise tax revenue by cutting loopholes and forcing large companies to pay more taxes - whether that'll work or have the desired effect is another question, and one I don't feel particularly qualified to answer - it would only give you a little bit of respite. Social Security and Medicare are set on a growth path that will rapidly make them take up such huge parts of the budget that adjustments in other parts of the budget will make little difference. One way or another, the growth of those two programs has to be radically slowed down - or else the government will rapidly find itself unable to fund other important services. And frankly, I'm not sure merely cutting back waste and fraud will be enough.
