What a wonderful, utopian dream world you live in. If you REALLY think Trump would fix anything of significance, you are sadly mistaken (mislead, deceived, etc.).
Indeed - why is Trump in this at all? It is because he sees a profit. Period. Trump does nothing if it doesn't boost his wallet. Trump is in a no-lose position. If he runs and is defeated - he wins - money will continue to pour in. If he wins... then his stock goes even higher. Historically, Trump has been no champion of Conservatism - not by a LONG shot, often falling squarely on the opposite side of the political fence. He is a consummate business man - he knows how to sell - and that is exactly what his current schtick is - a huge sales pitch (I call it a SCAM). He is pressing all the current hot-button issues and doing it loudly. Don't believe anything he says is his genuine position. A salesman will say what is necessary to close the sale.
GO TRUMP-CRUZ 2016!!!!!
