Mass Deportation? Out of who's pocket?

Whether or not Trump is genuinely serious about the mass deportation of 11,000,000 illegal immigrants, what I don't understand is:

Why is no one throwing the question to his supporters: who the hell do you think is going to pay for that?! 'Cause it's going be expensive as hell, you do realize that, don't you?

Even his supposed wall that he claims he'd make Mexico pay for, you do realize that what he's proposing is that the wall will be built, and then somehow he's supposedly going to convince Mexico to pay the bill, right? So who the hell do you think is really going to be paying for that wall?

And while I'm at it, let's talk about what he claims concerning the military. (I'm astounded that military personnel aren't appalled and insulted about what he says here.) Because he claims that he would also "beef up" the military big time. But again, who the hell do you think is going to pay for this so-called "beefing up" of the military?!

But, why does the military need "beefing up" anyway? He claims the military is ragged and thin, and is relying on old, shitty equipment that hasn't been replaced in decades, because they haven't gotten money from the government, so they're basically "starving" and they can't get access to the latest technology.
Excuse me?
If that isn't complete horseshit, I don't know what is.
The United States of America has the most powerful and most technologically advanced military in the world. And one of the most important reasons why is because our government, for decades, has been willing to pour billions upon billions of dollars into it! The military doesn't just have access to the latest technologies, the military is often the raison d'être for a lot of the latest technologies! Because the Department of Defense is one of the biggest contributors funding scientific research and development! (And mostly for the development!)

I'm not all patriotic and I'm not some worshiper of the military, so it's not like I have some personal interest or desire in talking up how awesome our military is. This is just the reality, and you don't have to look hard to find it!
The trash Trump talks about our military is so full of insulting bullshit, it's horrendously shameful and a disgrace.

But at the end of the day (or the end of this entry), the question remains: who the hell do you think is going to pay for this supposed "beefing up" of the military? Seriously, do any of his supporters ever wonder these things? He goes on and on about how much money the Democrats have spent and added to the national debt, and yet the shit he says he's going to do as president would cost ridiculous amounts of money!

Not to mention the money and lives he would cost sending us to war with Daesh, since he claims he'd make sure we completely demolish them. But I've talked about this before.
