We can point fingers at the rich for making more money but really we should be hounding our government for wasting money. All the taxes and confiscation in the world won't fill this bottomless pit

Just today:

"£700m nuclear conservation plan would save one salmon every 12 years"

Your government is not "wasting" money. It's intentionally putting money in the hands of the rich for a personal kickback to the involved politicians, under the guise of incompetence for plausible deniability purposes.

My question is: does this tax money get spent on the poor, or is making the rich richer?

Both. Today's rich are wealthier than the rich of the past, but today's poor are also wealthier than the poor of the past.

It's also the case that quality of life differences have shrunk between the two groups, not because life has worsened for the rich, but because it's improved for the poor. Bill Gates' car, music, TV shows, phone, pants, meals, etc. aren't that much better than the average person's, today.

In the UK, it seems that it's mostly spent letting the boomers live long and relatively luxurious retirements that younger generations can only dream of.
