This is at best naieve. How can you possibly reduce all of the complexities of a nation's multiple economic wants and needs to that conclusion? This is the problem with the movement, myopic and idealistic notions of being free from work. Universal income basically drives up inflation, if you give everyone a free $10 everything becomes $10 devalued. Money works partly because it is scarce and takes work to accumulate. Other people want to exchange their effort for yours. If there is no effort, there is no value.
Even if the above is not true there are surely numerous other forces at play that don't fit in with your simplistic idealism.
If you think it's the boomers keeping you down, wait until all the YouTube and social media players get into their 40s and see how they feel about giving away their wealth. People are greedy, selfish, family first, and tribal regardless of a generation.
