Well if the boomer was a white male yes you are correct. If he was a minority or a she not so much. I am also not so sure about that. Where I work I work with a lot of millennials. they are all making 70k a year a few are buying their first home just two or three years out of college. They work hard, invest, and are doing well. I even worked with an intern and he took a job offer from my income and will start this June when he graduates. If you think 70k is not a lot of money I would disagree since in my area a home is between 160,00 and 220,000 for a 3/2 and a bit less for a condo. It is not far from the beach and is home to a lot of tech companies. Yes, it is not California, Washington, or even Austin but those locations are crazy expensive and eventually, companies will build more campuses in lower-cost areas.
There are more than a few problems. One is you are not going to make a good living doing unskilled labor any longer. The second is a lack of vocational training. The idea that every kid needs to go to college was a bad idea. Plumbers, electricians and so on make good money without a degree.
One advantage may have been the draft. If you did not do well enough in school to go to college you got drafted. Back at that time the military had a lot of manpower and did not farm work to contractors as much. You got drafted and if you had some brains you ended up learning mechanics, electronics or even how to cook. If you did not want to get drafted you worked hard in college and picked a subject in math, the sciences, or education. Also after you got out after being drafted you had the GI bill for education and for getting a home loan.
You have X amount of opportunity and you now have people of color and women competing on a more even basis. More people competing for x jobs means it is harder to make as much in that market. We are lucky that some new jobs are opening up in new areas but they require more education than working on an assembly line.
Second of all my parents who were just before the boomers but close enough and I am the first year of Gen X. just for the record did have a lot less to spend money on than we do today. They did not have cell phones, Only two TVs one in the family room and one in the living room and no computers when I was a small kid. Video games? nope. Music subscriptions? Nope, we had a few records and radio. All those things were not available to mere mortals in the late 60s early 70s.
So you have better opportunities for minorities. A far larger selection of entertainment. Easy access to both data and a mindnumbing amount of computer power for next to nothing. You have a larger selection of different foods and cultures. I often wonder if a lot of millennials' viewpoint is distorted by an idealistic view of that period that tv shows of the time and later showed as well the visibility of the well to do boomers of today. You do not see all the older minorities that died young or are living in extreme poverty today. And before you jump to blame the Boomers for that it was the Boomers that started the changes to make those things better. The boomers did not have it all that easy. You are not facing a daft. You are not living with the threat of nuclear war hanging over your head every day. Yes I know we still have nukes and still need to worry but not like they did in the 1950s. You do not need to worry about Pollo unless the anti vaxers keep going. Technology keeps getting better new types of fission reactors could solve many of the problems of power generation. Fusion may actually become practical soon. Medicine is getter better if not cheaper. You only see the problems of today and only the good things of the past. That is just human nature but it was not as good in the past you think it was and the boomers did not have it as easy as you think. Today is also not as bad as you think it is. So much good is going on but fear sells and is fear and anger are great tools to use to manipulate the masses. And yes I mean both sides us it with abandon.
Of course, the flip side is also not true. It is easy to see the idiot millennials and think all millennials are like that. And yes millennials are young and even many of the educated ones are fast to jump to conclusions anger and meme mentality. They lack experience and wisdom because they are young but that will change for some of them. I like a few millennials, find the vast majority somewhat disappointing, and find a few really tick me off. Pretty much like every group on the planet.
Have a good New Year and try got get a bit more historical perspective. I also suggest you look at all the good that has happened since the 1950s and thank the boomers. Also rember that the president that signed the EPA charter and the Clean water act was no other then Nixion.
