Yeah, well you don't have a clue either.
I could be drunk and in a comma and I'd still have more of a clue than you.
They pay payroll taxes of 7.65%. (FICA 6.2%; Medicare 1.45%)
They might have federal income tax withheld but they get most, if not all of it back when they file their return (presuming they take advantage of all the rebates and credits) If even they don't get anything back, a single person with no children earning $7.25 an hour working full time would make $290 a week and have $17 per week withheld. That's a 5.9% tax rate.

They pay sales taxes.
If they own a car (unlikely) they pay gasoline taxes and license tab fees.
If they own a house (unlikely), they pay property taxes. They would get a good chunk of that back when they file their property taxes.
So please tell me how these taxes could possibly add up to
one-third of their income?
Most poor people don't get property tax refunds. Someone earning minimum wage pays upwards of 10% of their income to property taxes for a modest home and car, unless their possessions are utterly modest. (Why should poor people be have to be homeless just to avoid you claiming they don't pay taxes. If they rent, they're still paying property taxes, and their cost of living is higher than owning a house.)
Poor people pay the highest percent of their income to sales taxes, which are roughly 8% when they do pay it.
I pay $720/year to city utilities before even a penny of cost is added for utility consumption. That's a fixed expense, regardless of how much I earn or consume.
The working class pays double what you think for payroll taxes. The nominal employer's portion is still the worker's earnings. FICA and Medicare also aren't the only payroll taxes most people pay.
Then there is the 5.9% effective income tax rate..
Minimum wage full time is about $15,000, and adding up all this comes to almost exactly a third of that.
And I still haven't gotten to extra taxes they pay on such thing as phone service, gasoline, and alcohol.
But, many poor people don't get $15,000/year because most employers don't give unskilled workers anything close to 40 hours/week, even if they pay them a bit above minimum wage. The percentage of their income that goes the government increases as their income goes down.
