The OP hints of the reality. The budget is intended to be BS, and most presidents would do this. He's put things in there that have already not gotten traction, he knows it won't.
What you're seeing is evidence of how government doesn't work well, with the buden of running too much of our economy. Too much is tied up in politican's hands. Goes for repubs too, Bush was probably the single most incentivized person on earth to NOT increase taxes...but he did. That's how broken government is when trying to centrall plan an economy.
What's going to happen is everyone including Obama will ultimately ignore that budget, and they won't take action until after the election, ouch. Of course, a system that can't function on a routine basis because of elections...well that's a broken system, and you know it. But once elections are over, they will meet in back rooms where we can't judge their behavior, and they will work out a compromise on budget. And the theme of it will be, kick the can down the road again. You know it, I know it.
That's how they work, not because Obama is incompetent, but because that's how a political government functions...like a crazy idiot drug addict, with bad manners. If I hate Fidelity investments, I take everyting out and move to UBS, or hell, hire someone to deal with Fidelity. I have choices, I can make immediate corrective action, I can make it work. Govenment? We're all just watching the tragedy infold year after year. I say tragedy only beacuse they have so much of our wealth to fumble around with. Cut them down to $1.5T budget and it's just a sad drama rather than a full blow tragedy...tolerable.
The never should have passed permanent hand-outs in the form of our modern entitlement programs. It should have either been unconstitutional and ensured to be in the future, or it should have been a temporary measure due to a specific, transient, crisis. Instead, they leveraged crisis to make it permanent, and now you can never get a majority to go take money from seniors. You have to ask the younger generation, to sacrifice EVEN MORE to pay them off...well, **** that, you know what they will say? Let's just kick the can, just like they taught us how and showed us it was OK.
