Did you know that the Federal Government still collected an increasing amount of revenue every year, despite the Trump tax cuts on individuals income taxes?
When I think about corporate taxes, I consider whom actually ends up paying the costs for those corporate taxes. Business and corporation inevitably passes on the costs of their taxes onto the customers and consumers of the goods or services provided by those businesses and corporations.
As for your ideas concerning social security higher age requirements, that's an idea which makes a lot of sense to me.
1) An increasing amount of revenue isn't relevant. We have more people and a growing economy. Government spending as a pecentage of GDP or even per capita is smore relevenat.
2) What the government spends money on is more important than the amount or even percentage. I would be more than happy to pay higher taxes if those in need received needed benefits. As a country, we very low taxes and very low levels of service.
3) An increase in higher taxes on the rich or in corporate taxes does NOT automatically get passed on to consumers. Prices are determined by suppy and demand. You simply can't just decide to charge $20 for a buger because your costs went up. Well, you can, but you will fail as a business. Besides, corporate taxes relect costs. Some think that it was just aweful to increase the minimum corporate taxes rate to 15% as middle class earners pay much more (please include income and payroll taxes).
4) It is simply morally wrong for taxes on earnings (income plus social security taxes) to be higher for bosses than for workers.
5) Military spending is difficult to analyze since so much of the cost is overhead. Also, in the end, we have to decide whether we want to be one of leaders in proactively moving to keep the peace, or whether we want to be reactive and fight the forever wars. And just BTW, many countries in Europe spend a higher percentage of their GDP to fight Russia in Ukraine. Our contributions are very, very small compared to to the ridiculous amount we spent trying to impose our will on Iraq and Afghanistan (and Viet Nam in times past).

BOTTOM LINE
We can afford whatever we want to afford for whatever goals we wish to spend. As a country, we need to decide on goals. We have decided that leving more income for the richest among us so that they can buy their yachts and pay their dog walkers is more important than using government money to provide the middle class with a living wage for those working full time or more than full time. We do deem to accept that the veryu poor should be provided for, except for the obvious deficiencies in medical care, education and public transport.
