One of the main issues is that a lot of advice is presented as an unconditional, absolute guarantee to success. A college degree was never a guarantee of future success (contrary to great-grandparent's assertion), but the push to get everyone to get a college degree has rendered its utility as a helpful marker much more useless. Similarly, the ability to start your own business is difficult for most people, but even for poorer individuals, it is possible to start, say, a cleaning service with very little assets. (At the same time, such businesses are unlikely to make a whole lot of money at the end, but you might be able to move from working class to middle class, e.g.). A lot of contractor businesses--your plumbers and the like--are going to be from the lower middle class or middle class, and you can make some good money there, although that is also likely to be at the cost of your health much sooner than you expect.
This is not a super relevant statement as it can be made with a single example - the rate of mobility is down relative to when those who'd give the advice experienced (which has been compounding for at least the last 30 years, some say since the 1970s).
According to one economist in 2020, in the U.S., absolute mobility, the chance a child earns more than their parents, has fallen from about 90% to roughly 50%. Source: https://www.economist.com/united-states/2020/05/16/two-leadi...

Social segregation also plays a really important role too, and cross class relationships have plummeted - as someone who is doing well but didn't go to college, the relationship building in college is a factor that will work against me my entire life.
I would never say that upward mobility is impossible, or that its not worth it to strive for it. I am saying that dismissing headwinds due to no guarantee of success doesn't really take into account severely constrained actual access to opportunity that continues to become more constrained over time.
Life is usually a struggle. No one should expect any different.
I think this starts to make an inferred narrative about how failure is inevitable and that its excessive complaining, when there is large amounts of data showing how it is genuinely more difficult.
Just your Ukrainian example, it was cheaper to live 25 years ago, the cost of college has gone up ~180%. Since 2001 incomes have gone up 64% while housing has gone up 136%, healthcare up 180%, food up 100% and transportation up 120%. Thats a different playing field.
The point being made isn't that failure has any inevitability. Most people will be able to make it work enough to live, and those who can't due to choices, trauma, disability, drug use, or excessive bad luck are the homeless people you see begging on freeway offramps and intersections. At the economy level its a numbers game. It will never be impossible to make it big, in the same way that some people with every single advantage will end up on the street without a penny.
Today a dreaming Ukrainian is quite likely to instead get ripped away by conscription kidnapping teams and used as cannon fodder on the front, and not even make it to America. The reality changes but the rule of thumb is still good, you do the best with what you have and make yourself ready for opportunity you might not ever get.
