The problem is that the rich pay so little in taxes that their return on capital is greater than economic growth meaning they get richer (more of the pie) while everyone else gets poorer (less of the pie).
The solution given by economists and practiced in Europe is to tax the rich more so they make less and grow their wealth less compared to everyone else.
You don't seriously think that agricultural land is infinite? Or Gold is infinite?
But you think economic growth is infinite and "everyone eventually benefits"?
How indoctrinated can you poor saps be?
Perhaps you have not noticed that most of Western Europe has had little or no growth for a very, very long time? Do you know what the unemployment rate is in France, Spain, Italy, Greece, etc.? Do you know what the GDP growth rates have been for most Western European countries over the last 20 years? The few European nations that have experienced modest growth have done so because they have adopted key fiscally sane/conservative policies (such as sound money, rigid tort reform, pro-growth corporate tax rates, and balanced budgets or minimal deficits).
