There's a bunch of sleight-of-hand and logic errors in this social media beauty.
First off, the $20,100 "paid by employer" is not a subsidy, it's part of the employee compensation package. Would anybody really believe that the employer is giving a gift of ~$20k without a corresponding salary deduction?
The only employee subsidy here is the tax savings on the $20,100+$6,850, or $26,950. At the 12% marginal rate I suspect the large majority of workers are in, that's a subsidy of $3,234, an effective subsidy of 12%, a far cry from the claimed 74%.
The $14,700 ACA subsidy is higher than the $3,234 employee subsidy, yet this nice graphic says it's smaller.
Part of the post says:
What it doesn't say is if the employee "subsidy" disappeared tomorrow, the employee annual pay would go up about $20,100 to offset what the worker would "suddenly owe", and the only loss to the worker would be the taxes due on that additional $20,100.
Unless you believe that the employers are currently donating this annual $20,100 out of the goodness of their hearts

Another example of how anybody can put crap information into a pretty picture and post it on the Internet.
