The great security against a gradual concentration of the several powers in the same department, consists in giving to those who administer each department the necessary constitutional means and personal motives to resist encroachments of the others. The provision for defense must in this, as in all other cases, be made commensurate to the danger of attack. Ambition must be made to counteract ambition. The interest of the man must be connected with the constitutional rights of the place. It may be a reflection on human nature, that such devices should be necessary to control the abuses of government. But what is government itself, but the greatest of all reflections on human nature? If men were angels, no government would be necessary. If angels were to govern men, neither external nor internal controls on government would be necessary. In framing a government which is to be administered by men over men, the great difficulty lies in this: you must first enable the government to control the governed; and in the next place oblige it to control itself. A dependence on the people is, no doubt, the primary control on the government; but experience has taught mankind the necessity of auxiliary precautions. - James Madison

No. It's a problem of excessively-corrupt, under-regulation of individual greed that only a professional, more "angelic," functional, legitimate, ethical, and sensible human social structure (government) can and must limit fairly to prevent a few individuals from hoarding treasure and destroying others. When a few rich individuals effectively own the government in all but name, they own enough power to make it do their bidding and block anyone else from challenging them. They will never relinquish such power willingly because they "need" it to protect themselves and their greed and entitlement makes them believe it's theirs alone. Revolutionary communism probably isn't the answer, but revolutionary sensible something else might be. There is no other way except extremely clever chicanery to remove the influence of billionaires.

Nothing has changed in the principles or human nature; only the culture, fashions, laws, power, technologies, income, and wealth distribution... and especially that nearly all of the controls have failed pertaining to the regulations of gaining and amassing excessive wealth (taxes and such), and purchasing influence (campaign finance reform, etc.). Thankfully, there is not yet an Emperor who decided to not leave after their term, so some controls on power related to government are operating as designed (but for how long?)

Revolutionary communism or similar without full control would simply assassinate one billionaire after another until they understood the message clearly: that their personal survival depends on them returning a large fraction of their looted treasure and all control back to a government independent from corporate influences.
