One of the economic lessons from the Soviet Union was from farmers.
There was a reduction in the field production rates, turned out the farmers had no incentive to do much more than not be yelled at by the government, so the fields would look great on the outer rings near the roads that the 'managers' would drive and the inside was shit. We have better tech to watch people now, but at the end of the day it is the same, people work harder when they have something to gain (or lose) from it. Any ceiling is going to eventually be arbritrary and counter productive.
I disagree with the 'it isn't working bit'. This is a great propaganda trick:
Notice, 50.3% down to 42.2% is being shown here as the Median, or just the very middle number and the area around it (which seems stupid but whatever without have the full dataset it is all smoke and mirrors).
So they use this to say the size has fallen.

50.3% of 205.1 million is 103.1million people, 42.2% of 309.3million is 130.5 million people
So 30 million people have been added to the middle class (according to this measure) since 1970.
This is how this propaganda game is played. Which argument are you trying to make, mangle facts to fit it, write bullshit articles with these stats, and sell it (by having online tools flood every feed you read with it) to you in whatever 'camp' you decide to be in.
I can either say, 30 million people have been added to the middle class since the civil rights movements of the 70's.
or as in the 50 years that those libs took over, the middle class has shrunk by 8%!
