And you think those are not achievable on $7/hour?
They are not. At least not in Portland, and I suspect for most of the country.
The average price for a 2 bedroom apartment is right around 700/mo, for a really cheap sketchy place.
That alone is about half of a minimum wage paycheck.
Add in a $1000 dollar beater that needs fixing every 3 months, let's say about 150/mo unless you're unlucky.
Insurance.... Well that depends. Can't really generalize that.
But that leaves just 350 a month for gas, food, and insurance, assuming you have no unexpected expenses, like your shoes crapping out on you, or a theft, or something.
Now I think food should include healthy food, proving adequate nutrition for a 2500cal/day diet, including complete proteins, and sufficient vitamins and minerals across the board to support a healthy adult. Depending on where you live, this gets expensive, as you must also factor in gas spent getting there.
And gas was getting pretty bad for a while. Especially since a lot of the old beaters don't get great milage.
Secondly, 8hours rest should be a requirement for a healthy lifestyle. Sleep is surprisingly important to mental and physical wellbeing.
Depending on where you live, you're going to just make it, or just fall short.
And what about wanting kids? Sure you'll have your spouse's income after a while, but a kid also carries a lot of expenses. The answer cannot be, "well just don't have kids". There should be no monetary requirements for fulfilling the primary purpose of life. Otherwise you're essentially saying, "you're just too poor to live".
And let's get down to the bottom of the issue. You're essentially saying minimum wage workers aren't contributing enough. This makes sense from a purely subsistence standpoint, but the developed world is no longer at that point. We have the capability to provide adequately for everyone.
It doesn't even seem to carry any significant economic costs. Germany, the 4th largest economy, the largest in Europe, does a far better job than we do at providing not merely life, but a dignified life to all. Despite the fact that, at least on paper, they have less money per person to spend.
