One reason public policy favors employer-based health benefits instead of individually owned health insurance is the former is supposed to equalize access to health care among workers of all income levels. Insurers usually demand 75 percent of workers be covered, which leads to benefit design that attracts almost all workers to be covered.
Employers do this by charging the same premium for all workers but only having workers pay a small share of the premium through payroll deduction. Most is paid by the firm. Last year, the average total premium for a single worker in an employer-based plan was $6,435, but the worker only paid $1,129 directly while the employer paid $5,306.
Although this suppresses workers’ wages, workers cannot go to their employers and demand money instead of the employers’ share of premium. The tax code also encourages this, by exempting employer-based benefits from taxable income.
