If you were to reform the US, what changes would yo make?

Id create a national coaster transport powered by kite power separate regional tracks and a turbo coast to coast track also id dissolve the electoral college. Have a flat tax and tax incomes of religious leaders after their first million$. Individuals not parishes or worshippers. Id try to convert all abandon buildings to affordable housing and legalize all drugs with only age restrictions. U can smoke meth at 45. Might be an exanple. Finally id cut the pay of the legislature since its a part time job and cut the military budget by about 20-25%. All are game changers!
