Is it normal my family is a failure

I am the youngest of the siblings, each year our family has seemed to get poorer and poorer. Our family used to have a combined worth of millions and now we are degraded to the point of selling all of our things on craigslist.it all started in the 2000s (2000-2009), a decade of disaster for us, our father left his high paying job so he could spend more time with the family, but ironically our loss of most of our wealth because he left the job resulted in him having to work more hours then ever, eventually leading to the crumble of my parents marriage. First the siblings began to disperse, once they hit 18 and they moved out and far into the city outskirts leaving me alone with my parents. Then as we hit the height of our financial ruin the parents split up not just because of a mutual distaste for each others money management abilities, but also due to my fathers adultery which may or may not have resulted in illegitimate children. We are not exactly broke now but we are clawing our way out of the hole of what was financial remains. We don't exactly own anything anymore and went from pretty well off to the poor house without even touching middle class. At one point, by the end of the decade, we were living in a cockroach ridden, bed bug filled, cheap motel. We would never imagined that EVER, and thats what became of us.

I am left with a feeling of only pain and failure whenever i try to bring this family back together for an event or a dinner.It seems as though as everyone is pretending this is common. My parents often tell me to lie to the extended family in other states when they ask about how good things are, so we can "compete" with them. On one visit to the relatives they showed me pictures of their annual barbecues and joint vacations to the Caribbean. I put on a smile as they told me about their great trips, but later cried myself to sleep at night as i compared my life to that of my cousins.

Now fully grown, I am contemplating just giving up on these these people, as there is so much shame and conflict still going on that its practically is no longer worth it to even try. I'm considering moving to another city when my financial ability to live there is in order. I want to start over with my own family (wife and kids) except I don't want them to go through what i went through. My siblings disagree with me when i complain that every family is like this, I want to give them proper example when I leave for a new city/town.does my plan make sense?
