Raising taxes is really not part of the solution because increasing tax rate rates will likely not yield more tax collection.
The real problem is immense spending on seniors to live a free life
Unfortunately you are wrong. While people don't "own" a pension, they do get government payments for life after they hit age 65 as long as they (very minimal) work to earn an income during their working years. (This is social security). They also get free healthcare for life at 65 and if they are unable to pay for full time round-the clock hospital care they get that free too (Medicaid).
All-in the US governments spends $2,700 billion per year on seniors which is nearly triple the defense spending.
>increasing tax rate rates will likely not yield more tax collection
What's so special about our current tax rates that you're making this claim? Because if you believe that higher tax rates don't yield more tax collected, why not argue for tax rates to approach 0%? So either you're couching your real and unpopular opinion like I described in my first comment or you're claiming that our tax rates are optimized for tax collected.
