In Medicare, senior citizen’s healthcare is subsidized by the taxpayer.

This statement is 100% wrong.
The word "subsidized" is used inappropriately.
The proper word is "funded"

"Taxpayer" is used ambiguously, too.
The proper source is the working taxpayer through contribution by his employer AND deductions from his earnings. No workee no Medicare.

That is true. Trustfunders and people who live on the earnings of others do not pay.
