One benefit of national health insurance that David M. Gordon ("National Health Insurance Would Be Cost-Effective," June 17) failed to mention is its portability from employer to employer. Our current system provides health insurance, pensions and similar programs on a company-by-company basis. When employees change jobs they often discover that significant benefit losses are entailed.
For example, at a new job an employee may discover that his or her previously insured medical conditions (or those of dependents) are not covered because they are "pre-existing." Pension formulas are often arranged to penalize employees who leave in mid-career. The contrast with Social Security is obvious; under that national system employees can change jobs without any loss of coverage. It is 100% portable.
