The top decile and bottom already are below that ratio. ~90k gets you to the top 10%. 10k puts you at the bottom 10% (not a full time worker). The problem is really the wealth of the top 10%.

See the top households:

Net Worth of the 10%, 1%, and .1% Households Percentile Threshold 10% 2% 1% 0.10% Net Worth $1,182,390.36 $5,816,220.17 $10,374,030.10 $43,090,281.00

The top 1% owns 35% of the wealth in this country. the next 9% own 40%. The bottom 50% own 1.67% of the wealth. That's the problem. Most people are paycheck to paycheck with little opportunity for wealth creation / stability. Most of this is inherited wealth; the wealthy today, across not just the US, but the globe, are largely descended from the wealthy of many generations past. There's a great study on the gravity of wealth from the UK:
