For those who want viable solutions, this is how governments elsewhere operate (In general).
1) Reduce (government) demand.
2) Subsidize, review taxes downwards etc.
3) Offer cheaper options.
For example, did Obama demand that hospitals should charge less so that everyone can afford medicare?? Of course not!! Come up with policies to ensure everyone is covered, equip government hospitals to ensure no one ever NEEDS to go to a private hospital etc.
Have Germany, US etc. demanded that private schools and universities reduce their fees? Nope! Just ensure public schools and universities are equipped and staffed to a level that they can compete with private schools and Universities.
Netherlands - You would never imagine of being a landlord! Why? The government - central and municipal - have built enough houses and ensure that everyone who needs a house gets allocated one. And they are affordable!! When you turn 18, you sign up with the Municipal and they get you a house. They do the same with education, medicare etc. If you have a job, you pay for cover. If you don't, the government figures out what to do.
Do most developed countries have to deal with "matatu menace" and pricing? Nope! They have ensured public transport is well catered for - trains etc.
Examples are endless. You have to decide if you are a Capitalist nation with free markets or a Communist/Socialist country.
Even fuel price controls would have been addressed very easily without the "control" part. Just ensure there are National Oil stations all over the country and have them sell fuel at the lowest commercially viable price - the government can control the price being the owner. If the other petrol stations continue selling at plus 10 bob and Kenyans go to fuel there, no problem! So long as those same Kenyans had the option to buy the same fuel CONVENIENTLY at a lower price, it is okay!
Never count on making a good sale. Have the purchase price be so attractive that even a mediocre sale gives good returns.
