Everybody I know who’s under 30 is broke

lol, I lived paycheck to paycheck in my 20’s. I bought a house at 23, started a family at 26, worked my ass off and now we live comfortably. We’re not rich, but we will bring home more money in retirement than we do now. My 20’s were during the Obama years so if I can do it, kids today can too.

Definitely more difficult today than in the recent past.  I'm not saying it is impossible, or nearing impossible, just that it is more difficult. And it being more difficult isn't an excuse; those under 30 have far more opportunities available to them if they are willing to go for them and are smart about their choices.

I want to point something out first...  You called out the victim mentality in the post I quoted...  And then you immediately claimed victim status; i.e. that I was somehow labeling you as the problem because you are wealthy.  Where did I blame you for being wealthy?  This country is awesome.  I am happy that you are successful.  I consider myself to also be successful.  We're not the problem.  But I somehow blamed you?  Can you point to where I blamed you, where I named you as The Problem?  Or is it others labeling you as the problem?  And I'd like specific examples of that as well.  

I certainly agree that when you're in your 20's, you cannot expect to have a high net worth (or even a positive one in my case, and probably yours).  Things changed in my 30's and now in my 40's I am well off.  I imagine that is the case with you as well.

But it is more difficult.  The costs of housing, education, and food have exceeded wage growth.  Especially in the past couple years, but the trend isn't anything new.  That makes things more difficult.  Period.  As I stated, there are so many opportunities available that things being more difficult isn't an excuse for the individual.

I 'member a time when people were saying that if you just stopped buying the newest IPhone, avocados, and Starbucks that all of your financial problems would be solved. 

I don't hear that argument anymore.

Assuming that is true - and I have no reason to conclude otherwise - why do you think that is? 
Not enough income?
Not enough skills to earn more? 
Too many expenses?
Other factors? 

Rather than painting with overly broad and simplistic broad strokes with unproductive bromides such as "victim mentality" and questioning the work ethic of those under 30 as we have seen introduced by some in this thread, the issue you raise is an important one. 
This country has been very good to me and offered an environment for wealth production of which I was able to take advantage - as is true for many others as well. 
But it would be unfair, unkind, and irresponsible to ignore the reality you shared above.
Homes, apartments, food, utilities, insurance, automobiles, clothing, medical expenses, higher education, debt, and many other things have indeed become very expensive and that does disproportionately impact those individuals who have not yet had as many years to accumulate wealth and is making it harder for them to do so.
It is not helpful to disparage them nor to give a self-serving pat on the back to those in better circumstances.
To be serious about the problem, we must address two things.
Why has this happened (particularly, but not exclusively) over the past 5 years?
What do we do about it?
